The ability to ride has everything to do with personal circumstance; kids, sick relatives, job and also proximity to decent riding all effect the amount of time which people can put in.
Whilst sick relatives are things that just happen to people, and kids are things people have, the rest of it is all personal choice - what job you do, how hard you decide to work, where you choose to live.
I would love to not have to be away from the house for 15+ hours a day and have perfect trails on the doorstep. Not choice but reality for me.
Like this - you choose a lifestyle that requires 15 hour working days, you choose to live somewhere without trails to ride.
Obviously for some biking is not a high priority in their life choices, whereas for others it is, but that doesn't stop most stuff being a choice.
Personally, whilst having a kid has curtailed my riding a bit (and other unavoidable family stuff somewhat more so), I've still done 6 hours riding since Monday plus a quick 6km offroad jog up the hill. I made the choice to go down to 4 days a week, so Thursday I'll go riding with my daughter. I chose where to live partly in order that I a)have trails from the door, and b)I have a nice ride to work. But they are all choices, and doing fun exercise is a high priority for me.
