Your first lines are not unconventional, I agree...
But you continue with arguing Bitcoin will selfregulate to enforce smallest transactions due to cost efficiency?
To argue it is up to the user what is worth transmitting on chain, and that the user should have the freedom to transmit larger transactions than minimally needed (multi sig).
But the core problem is the blockchain size is a performance aspect, just as block size is.
And the bigger the blocks I've or blockchain the less decentralized Bitcoin will become (potentially)..
So as I have learned from the blocksize war decentralized is the most important feature.
Thus we have to limit the blocksize and blockchain to a minimal but workable size.
So functional requirements (multi sig) ahould be allowed, while adding pictures is not functional (and some will disagree to that since it was very profitable to do so for a while).
So we can't surpass the need to define what is allowed/makes sense. And better error to the low side to extent it if needed.
To state Bitcoin is a self regulating system based on efficiency ignores bad actors that can spend endless money to disrupt Bitcoin ?
