I'm not convinced that abolishing marriage would end the wealth-redistribution system.
I'm not worried about the external social part of it, but the personal part of it is that many people (including myself) enjoyed both getting and being married. Obviously, YMMV.
I guess that marriage has some "legal framework" but I've never even thought of it in that way. To me it is a personal declaration of two-way commitment, made in front of friends and family, and it's worth as much, and as little, as how you live by it. Same as any commitment, I guess.
I like being married. It's not a charade to me. If you don't like me being married, because you don't like divorce lawyers, so be it.
