Yes, I agree.
Friend of mine, his daughter married her long term partner (both in mid twenties, been going out since school, living together etc) last summer. Flash do, in Mauritius.
You guessed it, six months later, they'd split up. God knows what their motives for getting married were, I wonder if there were cracks and they thought it would save the relationship. My friend reckons the lad just suddenly wanted his carelss youth back. As it is, all that money wasted...
If I ever find someone I love enough to marry, and he wants to marry me, well, that'll be nice, and I'd probably want a simple registry office thing and a bit of a party for our mates. At my age, a big frock and all that seems daft. But I'm quite happy not to get married, if the other person wasn't bothered.
As for the OT, yeah, I do tend to check out the ring finger when I meet a guy (and we're talking work or general social stuff here, not a dating type scene) but all it teels you really is if the guy IS married. If he ain't wearing a ring, he still could be, or he could simply be in a committed non married relationship. So it's not really all that useful.
