📝 Original message:I'm no authority on the subject, but I don't understand why there is a max
block-size, other than anti-spam measures.
The only other reason I have heard for a max-block-size is to force people
into paying higher fees.
This seems like the wrong way to force fees. If you want to force fees,
then do exactly that - make fees required, and set a minimum... don't force
people to pay fees by limiting transactions per second. That's like
shooting yourself in the foot to get free surgery....
