Marketing initiatives have limited windows. This matters, perhaps,
when you're some VC pumping cash into a startup with the hopes of
being the next stockmarket pump and dump darling. Outside of that
people use whatever they use because it works for them.

And by the numbers Linux desktops are more common than they've ever
been— and certainly Linux kernel _systems_ half the people I know have
one in their pocket and its hard to go more than a few hours without
touching one. To some extent the "Year of the Linux desktop" is a bit
like the "Year of being able to turn lead into gold" ... we can turn
lead into gold now, but the particle accelerators, atomic power, and
atomic weapons enabled by the same technology are far more interesting
due to the particle realities of this. So we didn't get the ubiquitous
Linux desktop: We got the ubiquitious Linux server, the ubiquitous
Linux-kernel smart phone, the ubiquitous Linux television, media
player, HVAC controller, etc. instead.

Desktops— well, that didn't meet people's hopes though I think not for
the lack of marketing on the part of Linux, but because Apple stepped
up and produced middle ground products that attracted a larger
audience. Especially as MSFT dropped the ball. They did some things
better, had a running start, and had a non open source software
business model which made reaping rewards easier.

But I don't see how any of this has anything to do with Bitcoin...
Except for the point that if Bitcoin doesn't become the money system
everyone uses and instead becomes the money system infrastructure all
the systems people use depend on— just as Linux has with the desktop,
where it might not be on the desktop but its in router firmware, cloud
servers, and just about everything else— I wouldn't consider that much
of a loss.

Bitcoin already missed its first— and perhaps only— fad window in any
case. Today people say "Bitcoin? Thats still around? I thought it got
hacked". ... thanks to compromised centralized services.

Every man and his dog? Perhaps not. But as many as can— probably so.

If we depend on the organic need for full nodes to overcome cost and
effort to run one there will always be major incentives to let someone
else do that, and the system would have its equilibrium right on the
brink of insecurity. Perhaps worse, since insecurity is most obvious
retrospectively. Security doesn't make for a good market force.

Tor is a distributed but controlled, by a small number of directory
authority operators, system.

It is a good system. But it has a trust model which is categorically
weaker than the one in Bitcoin. If you want something where a
majority of a dozen signing keys— hopefully in the hands of trusted
parties— can decide the state of the system you can produce someting
far superior to Bitcoin— something that gives near instant
non-reversable transactions, something that gives good client security
without the complexity of a SPV node, etc.

But that isn't Bitcoin.

And yet every tor user— if the have the bandwidth available can be a
full internal relay and the software nags them to do it (and also nags
them to act as invisible bridges for blocking avoidance), and every
user is technically able to run an exit (though they don't bludgeon
users to do that, because of the legal/political/technical issues
involved). To do any of this doesn't require a user to switch to
different software, and the tor project has previously opposed client
only software.

> So why should Bitcoin be different?

It's less different than you make it out to be— but it _is_ different.
Bitcoin is a distributed currency. The value of bitcoin comes from
the soundness of its properties and from the persistence of its
security. If the integrity of the distributed ledger is disrupted the
damage produced, both in funds stolen and in undermining the
confidence of the system, can be irreversible. Because Bitcoin's value
comes from confidence in Bitcoin and not from the specific
functionality of Bitcoins (they're random numbers that sit on your
disk) even if the ledger isn't actually compromised but people
reasonably believe it could be compromised that undermines the value.
Tor, on the other hand, is a functioning system whos value depends on
its current usefulness, and not the past or future security.

Compare in your mind— Say everyone just found out that at block
420,000 Bitcoin would stop enforcing signature correctness or block
subsidy values (and this wasn't going to be fixed), and you also found
out that one year from now Tor would hand over their sites, source
code repositories, and directory authority keys to Iran (and you have
no suspicion that they already had done so). How fast would you stop
using Tor vs how fast would to sell whatever coins you could?

I don't think we really can send such a message. Thanks just the same
as asking for donations, not completely unsuccessful but not easy to
make successful either. You're arguing for people running distinct
software which has no capability to be a full node, and changing what
they're doing in order to support the network. This maximizes the
cost, because in addition to the real cost the user must take a
switching cost too, and deemphasizes investing in keeping the full
node software as usable because 'oh just run a lite node if the full
is too slow'.
