Would you say growing wheat to feed your own farm animals should be regulated by the federal government? SCOTUS decided in Wikard v Filburn [1] that a farmer growing wheat for private use was in fact inter-state commerce. This decision has been used to uphold all manner of federal laws that on their face appear to regulate private conduct totally within the confines of a single state.
haven't countless of red American states passed age verification laws in relation to adult entertainment recently? Or is that different because there's only AI but no porn oligarchs in Washington?
It's not different and it should also be done on a federal level, instead of 50 different governments passing random crazy internet laws. When you have to do compliance for hundreds of laws in 50 different states it basically becomes impossible to do it and you end up in this weird position where you're probably breaking a law somewhere and you don't even know about it.
The founders' conception of "freedom" was different than the modern "anything goes" version. It was closer to the idea that moral and disciplined people could be trusted with freedom. As John Adams said: "Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
