I don't think disabled golfers are a big factor in this. First, there aren't all that many disabled golfers even in the villages. Second, every golf club in the world has this problem to some extent not just those with many disabled golfers. Third, the able playing partners almost always rake the bunkers for a disabled player (if they even hit out of bunkers, which seriously disabled players don't).
I think the biggest factor is the "broken window effect". Once a bunker with unraked footprints is encountered, the following players mostly don't rake it either.
With pitch marks, its peer pressure, if your playing partners all fix their pitch marks right away, you will too. So fix your marks, and your partners will too, as will the people behind you who see you doing it. People also fix ball marks without the reminder of partners doing it, just not consistently enough. I think weak hitters whose balls often don't even make a pitch mark, are the most forgetful.
