I have the right to use my camera to film adult content. I do not have the right to open a theater which shows porn to any minor who pays for a ticket. It's perfectly legal for me to buy a gallon of gasoline, and bunch of finely powdered lead, and put them into the same container, creating gasoline with lead content. It is _not_ fine for me to run a filling station which sells leaded gasoline to motorists. You want to drink unpasteurized milk fresh from your cow? Cool. You want to sell unpasteurized milk to the public? Shakier ground.
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.
