Permissionless systems can be best products. If it’s permissionless to participate in every part of the stack, and the protocol is designed around real time competition for every part of the stack, then the result will lead to the best possible product. It’s just f’ing hard to make sure adversarial participants can’t screw or up for everyone else. Solving these challenges is worth it because the big pot of gold is going to be won by the protocol that can single handedly provide markets for everyone and everything on the planet.
