Child porn is a serious problem in that it is abhorrent.
I have not seen any evidence that it is a serious problem in that it has significant impact at a societal level.
These bills are not being introduced to significantly reduce child porn. They're meant to further enhance surveillance powers or earn easy political points. Any actual effect on crime is a side benefit.
Let's not forget that the same people that propose these bills are the ones hanging out at Epstein's private island.
