It's true. The free-market can solve a vast majority of problems better than central planning can, and given a proper chance to prove it, likely all problems. But a free-market of software nodes making the decision is the ideal model for governing aspects like blocksize; letting node operators choose freely just invites people with bad incentives to abuse the freedom. People like Peter R try to gently imply they want the former, when in truth, they're proposing the latter.
