It would be amazing, but if you do the math, for example, you have one antminer S21 that does 470TH at 5000W.
Solo, your chances right now are roughly finding a block in 35 years with that hashrate.
Lets say power per kWh costs you 0.10$ (which is unreal cheap, but just as an example). That amounts to about 360$/month of electricity cost.
So are you willing to stake, for the next 35 years, about 150.000$ (360 x 12 x 35) for electricity for "maybe" finding a block?
Or would you rather join a pool and get regular payouts, so you can pay the electricity bill?
That 150.000$ has to come from somewhere, you need to have a job or something to cover that cost, for 35 years, to maybe find a block...
So solo is all good with bitaxes, burning maybe 20W - what the bitaxe consumes in month, you burn that or in one hair drying session. So its like a rounding error. But once you get some more mining equipment, it doesn't really scale well cost wise.
I think we need pools, just better pools, more p2p, more open...etc. Solo is fun, but it wont happen IMO...
