don't overthink it: miners sell block space
Discussion
yeah and that space needs to stay as cheap as possible as long as possible. it needs to grow in value naturally. plebs needs the option of controlling their own utxo's and taking self custody for at least the next 120 years. filling blocks with unnessessary data will make that impossible.
spam will never be worth much. i doubt it changes the average fee over time. in the long run its wishful thinking that everyone gets a utxo. that's why my scaling proposal is zero-utxo
what you want is people building value on an L2, and then making a utxo for "savings". this way they can wait for low fees to get out, and later back in, but in the meantime it's all L2
There always was spam and likely always will be. The question is how to deal with it in the most effectively while limiting negative impacts. Both sides have valid concerns. It's not black and white, good vs. evil. We need a rational plan and respectful discussions.
