I would assert that just as I have the right to pull out a sheet of paper and write the most vile, libelous thing on it I can imagine, I have the right to use AI to put anyone's face on any body, naked or not. The crime comes from using it for fraud. Take gasoline for another example. Gasoline is powerful stuff. You can use it to immolate yourself or burn down your neighbor's house. You can make Molitov cocktails and throw them at nuns. But we don't ban it, or saturate it with fire retardants, because it has a ton of other utility, and we can just make those outlying things illegal. Besides, five years from now, nobody's going to believe a damned thing they watch, listen to, or read.
I think you should continue to have the right to use whatever program to generate whatever video clip you like on your computer. That is a distinct matter from whether a commercially available video generative AI service has some obligations to guard against abusive uses. Personal freedoms are not the same as corporate freedom from regulatory burdens, no matter how hard some people will work to conflate them.
