as another comment points out, that is not the case everywhere, and people citing such "dilemmas" often fail to consider whether that is a desirable thing at all.

why should you be able to kick out all patrons who wear green shirts? is that not against the spirit of offering a public accommodation?

even if your goal is to enforce a dress code, surely that can be done in a "content-neutral" manner similar to the "time, manner, place" regulations.

similarly to the "constitutional fetishism" in the US, where people dig in their heels defending really awful features and design goals of the system, people often really fail to stop and consider the difference between the way the system is and the way it ought to be. Being banned from public society en-masse by a privately-operated "social credit" system is pretty horrible even if it's perfectly legal under the current law!

but it wasn't feasible to do that en-masse back in the 1700s, so nobody wrote a law preventing it, just like one cop could watch traffic in 1780 means that it's legally fine to build a massive database recording everyone's movements in the 2020s...
