It's alright, it is a touchy subject, and there's honestly random newbies every couple months who come online telling everyone to put their ball pythons in tanks/give them more room in tanks. So I think it's easy to jump straight to that response, because that is pretty annoying. Dr del also makes a good point... a surprising amount of newbies don't do "large setups" correctly, and encounter problems. So it's always better to push newbies to start out safe before venturing, unless you are smart.
And I see, it is a bit different for breeding purposes actually, because you want the snakes to interact and thus some breeders intentionally do smaller tubs, sterile, with nothing else. If you put too many hides and stuff, it actually lowers their chances of breeding since they can hide away from each other.they don't live like together like that permanently, only a couple days at a time.
