Well yeah, that's my point. Being in a marriage doesn't make someone more or less committed, invested in a relationship, caring or respectful towards their partner, or less likely to cheat or abuse or just be shit. It might have meaning to an individual or it might not, but outside or legalities it ls fundamentally meaningless. Like I said in my original comment, it's about the people in the relationship rather than the name you give it.
Exactly.
I'm not opposed to marriage (though I wouldn't want to do it personally). I think it's an incredibly useful piece of insurance and for some people it's a necessity.
The problem comes when people see it as some magic talisman which will guarantee emotional and sexual commitment. It doesn't, can't, do this. People who say they "feel different" after marriage may be right in one narrow sense but that's just confirmation bias. It can protect your assets in the event of adversity of various kinds, but it can't protect you against cheating, emotional abandonment, misalignment of interests and pain.
Married status in and of itself tells you nothing about the health or viability of the relationship: it simply tells you a contract has been entered into which makes it harder to separate. There are married couples with terrible relationships who are limping along because they can't afford to separate and non-married partnerships which are the strongest bonds imaginable and the status is not a reliable indicator.
I think in the case of genuinely well-matched couples who have stress-tested their relationships it may enhance a sense of well-being so it may have value over and above the contractual point. The problem comes when people treat it as a kind of universal emotional band-aid which they think will ward off evil.
If you go into it as a practical way of protecting yourself any enhanced emotional support is an upside. If you treat it as some sort of God-given validation of your special romance you are just setting yourself up to fail.
