Yes, but they're not that expensive to buy in bulk.

There are times when you just don't have one. My ex was a bit paranoid and would never have sex without a condom, so less fun was a non-issue. You can't safely store a condom next to your body, so keeping one in your pocket is sub-optimal. You can't leave them in your car for the same reasons. You can keep them stocked at home, but sometimes you end up at "her place" and maybe she ran out or you forgot to bring more over. Sometimes you go on a weekend trip and forget to pack them, but only discover this at midnight. Sometimes stuff happens, and in that moment, people will pay a lot to have one.
“…going to be used for purposes other than their intended one.”
I used to volunteer in an improv troupe sponsored by the local family services organisation. Part of that was doing issue-oriented shows, AIDS education, that sort of thing. We quickly learned that you can only hand out condoms to people in “serious mode”—if you do it right after a comedy sketch, there are slippery balloon animals on the horizon.
“…they make sex less fun…”
Depending on the individual, of course. I like condoms because they mitigate some of the sensitivity from multiple rounds.
Condoms are available for free at most health clinics.
I would guess that in most cases they are not used because they make sex less fun rather than because they are unavailable.
