General curiosity in some topic? I can talk quite a bit about firearms, ammunition etc. yet I never owned a gun, shot altogether maybe 5-8 rounds in my whole life (apart from BB gun).

I like watching youtube channels like Demolition ranch or Iraqveteran8888 for their technical expertise, viewpoints and just fun. Without any real expectation to ever own a gun to expand on this knowledge. Maybe some nice bow one day (which these channels don't even cover).

Don't expect everybody acting rationally all the time, considering cost/benefit against all activities, or similar.
