I understand your POV but porn is as bad as hard drugs (because it is). We clearly can’t regulate it given how many children get sucked into it. So letting government block this isn’t the same as government overstepping into other spheres of freedom.
Excessive freedom that hurts our species isn’t “freedom” but a hidden addictive trap that hurts us on a multi-generational level.
Porn destroys families which in turn creates broken children that turn to drugs, including porn.
Suicide rate is high with men and their depression is fraught with addictions including porn.
