the choice to bring the baggage is for self interests
I have to be honest with you, as libertarian I do believe self interest to be a virtue.
If a social blockchain is created on self interest by its founders, then they need to implement a protocol in such a way that will benefit them. But to get that benefit, they need HUMAN users. The more users, the more benefit.
If you create a failed set of rules on that new social blockchain, well, they will harm their self-interests.
So I don't see an issue there. Either their develop a good social blockchain or a shitty product. Time will tell.
But not everyone has resources to put theory into reality. I don't have enough resources to build an ideal (in my vision) social blockchain, so only can suggest others a couple of ideas and wish for their success.
