So what is the problem with creating a new blockchain dedicated to this project, if you are so convinced that it will succeed (apart from the fact that it would be the nth blockchain, and growing)? Why insist on using Bitcoin blockchain, especially when cons have been very reasonably argued already?
About the project itself, looking at the links you shared, you have done a good job so far IMO. You are addressing a real problem that has been giving headaches for a long time. I simply want to share my concern about creating a new problem by trying to solve an old one.
Firstly, It's not easy to build a new consensus. Creating a new chain, and attracting people to use a new chain is too hard, it needs much money to make the market. I'm only an independent web3 developer.
Secondly, I think saving my wealth and social network (the two most important things for me) in the same chain, makes me feel convenient.
Lastly, I just want use the consensus, which Bitcoin build already. It's good for this project to cold start. And inverse, the social activity gas can help bitcoin become stronger.
