Depending on the hobby, this is some fucked up gatekeeping.
My first thought was riding a motorcycle as a hobby, and that is one activity that many people severely underestimate how much expensive gear you should be wearing for your safety before you even consider doing it.
Helmet? What are you, some kind of weakling who has a brain to protect? Get a Harley, that's a motorcycle for us big overcompensators, and we don't do helmets, because there's nothing up there to protect!
