Distribution? Have you heard of the internet?
It's probably difficult to be paid well from Pornhub, xvideos, xhamster etc, but it doesn't take much to actually post across 5 or 10 or 20 platforms.
Difficulty would be finding partners willing to be on camera, getting decent shots, editing etc. It's not as if you need your physical video to be on shelf in a store is what I mean.
Getting and keeping eyes on videos and paying consumers would be more difficult
