Well until they ban porn with the bill that's currently making its way into law.
They kinda can't ban porn. There was an attempt to ban it age's ago in the USA: Though it failed because of the same problem than ran into with Prohibition with Crime Lords and other vendors taking control and corrupting the cities of Washington DC, New York, etc.
Legalizing it, on the other hand: They were able to make laws on what kind of booze could be sold, control alcoholic content, still get their tax money and people were more inclined to follow the law than to oppose something that denied the right of it.
A lot of gun owners in the USA that purchase their weapons lawfully go through the channels to own their weapons and even go through the background checks as a means of self protection or hunting or anything else. When it came down to the smut that could be sold, legalizing it to what was ok, what wasn't and so on was far better protection than what any politician in a diaper could bitch about in open forum as there are folks who follow the laws in what smut is ok, what isn't and they still get their tax dollar off of it.
And if it's being done because of 'OH, LACK OF BABIES MADE' or 'PROTECT THE CHILDREN!!' The former is an issue between Men, Women and our mass amount of issues between each other from the hell Social Media brought between Dating Apps and the controversies involving the 'Tea' App and the new 'TeaOnHer' App. The latter; people who engage with this shit going to far are being hunted down and are usually killed within the first few weeks of incarceration if they are discovered. Even then, everyone is pointing at the hypocrisy of Roblox now and the shit they are letting happen after they banned someone TRYING TO FIGHT THE PROBLEM IN THE FIRST PLACE ON A WHOLE PLATFORM!!!
... Right now; everything feels like someone is running away and trying to get away with what they can because the law caught up with them and their Black Swan Event they tried to trigger, mis-fired and blew their hand off. Now they are trying to cover their asses and run for that private jet to escape the consequences before they get shot out of the sky.
