My position on this is quite simple. Even if a family member of mine chose to take a job I did not like, I would still not want government to step in and prevent them from taking that job.
That's the difference between me and you- I don't expect government to solve my problems for me.
Do you expect governent to protect you from murderers? thieves? rapists? child molesters? terrorists?
The issue here is not that you don't want government to 'step in", because you Do want it to 'step in" to keep you safe. It's that you see no wrong in porn {depersonalizing and using people in order to act out dark sexual fantasies}.
