I do like what you are saying, but I also have similar concerns like @naturicia has mentioned. Phishing is one thing. Then, there is the trolling part when you add in the Resteem idea.
When STINC allows someone/people like the Steemit Doofus League gain so many accounts, it's just a recipe for future abuse. Unless, one wants to argue that they will settle down once they can earn without feeling shafted because they got called out for plagiarism, spam, etc.
Of course, if you can flag the Resteem post (as in flag the Resteemer), then maybe it's not so bad.
I think STINC needs to consider all the angles of abuse when designing and rolling out updates.
