if you're in a relationship at some point you should be able to trust the other to some degree or you won't be able to relax and enjoy it. there's no watertight way to completely assess the others reliability though, so you're always dealing with a certain amount of uncertainty.
sex tapes can be fun but are something very private, potentially damaging and a liability in case the relationship ends on bad terms (which can happen under the best circumstances).
so without (even flawed) protection like this you've got two options:
a) don't do sex tapes, which is not a good option in case you want to make sex tapes.
b) try not to let a leak affect you, which is not a good option because you're only human and part of a larger society where sex tapes aren't universally accepted (maybe with the exception of porn actors).
using this you have at least another level control/protection that might defer all but the most technologically versed (or at least prevent super high-quality leaks).
