the Constitution doesn't really empower the federal government to legislate individual behavior
A1S8: "The Congress shall have Power .. To regulate Commerce with foreign Nations, and among the several states, and with the Indian Tribes."
Since 1943, this power has been interpreted by every SCOTUS makeup (this isn't a "liberal" vs "conservative" thing) to include any imaginable human activity, unless they're explicitly blacklisted from legislating that topic (e.g. establishing religion or infringing the right to bear arms).
If a human can do x, then doing x almost certainly affects commerce. Did you just pick you nose with your finger? Then you just reduced the size of the market for automatic nose-picker machines, some of which might be manufactured in other states. If Congress wants to outlaw picking your nose with your finger, they have a constitutional basis for that.
If you disagree (and maybe you should!) then you have to accept that you are disagreeing with a consistent, unified SCOTUS, and not just today, but in your parents' and grandparents' time too. And that means you are guaranteed to lose any legal dispute (though not necessarily every philosophical dispute) over the matter, whether your (rather common sense, IMHO) analysis is faithful to the original intent or not.
I don't think this can be changed, except by a new constitutional amendment which re-asserts the 10th amendment by explicitly contradicting the current (1943-2023) [mis?]interpretation. Until then (i.e. forever), we're going to have lots of laws concerning individual behavior, and there will always be calls to have someone enforce those laws.
