What sort of examples can you bring up of custom marital contracts that would make people scream in horror? My guess is that people would generally feel queasy about allowing legal enforcement of what looks like slavish or abusive relationships. I think this would be a genuine cause for concern, not because I don't think that people should be able to enter whatever relationships please them in principle, but because in practice I'm concerned about people being coerced into signing contracts harmful to themselves. Not sure where I'd draw the line exactly; this is probably a Hard Problem.

I simply want more freedom to do things in ways that suit me and the other person as long as it doesn't harm anyone else. There may be gotchas and necessary qualifications once you get into the details, but the basic idea I think is hardly outrageous; surely there is at least room to move from the current stale state of affairs in that direction.

So I guess I don't believe the statement I quoted earlier entirely without qualification. Still, I like it because it recognises the fact that the current situation with marriage is ridiculous and it doesn't, in principle, have to be that way. That recognition, as opposed to taking existing absurdities for granted without even thinking about them like most people do, is what I was referring to as a rare dose of sanity:

"Yes," Harry said. "It's what you do to bad teachers. You fire them. Then you hire a better teacher instead. You don't have unions or tenure here, right?"

Fred and George were frowning in much the same way that hunter-gatherer tribal elders might frown if you tried to tell them about calculus.

"I don't know," said Fred after a while. "I never thought about that."

"Me neither," said George.

"Yeah," said Harry, "I get that a lot.

Your second paragraph serves... I'm not sure what purpose. To tell me that the idea is politically unfeasable? I know that.
