How the heck do people own full grown retics?

Im not trying to start anything negative, im just really wondering because it seems like so many people own young retics now days, they're all over youtube and what not.

Like...I would LOVE to own a retic but how would I house it as an adult? (still dont plan on it)

Wouldnt it require a zoo style enclosure? like something huge?

A retic just seems like too much snake for alot of people that I see owning them. I mean...as far as paying for an enclosure goes. I just picture a retic needing a room for itself! lol


enlighten me please!
