Society already imposes a dress code. Even without laws, a person that goes against the grain will be ostracized to varying degrees. People will refuse to interact with you or refuse to provide services or prohibit you from working for them.

Which is absolutely wrong. If we want to protect the liberty of all, then we must move away from such an archaic culture.

Even the amount of clothes is enforced as you can’t even just walk around naked without consequences in most locations.

This most likely will pin me as a radical, but I would argue that the right to nudity is extremely important and must be protected. Mark my words- you will see a social movement for this too once the other pro-liberty movements become successful-ish (like the LGBTQ movement).

But most US schools don’t have uniforms but they have you say the pledge of allegiance which is way weirder in my opinion.

Absolutely! Indoctrination at its finest!
