You can say that about any tool of power or oppression A lot of laws that are very necessary are tools of oppression, at least potentially. Yet no one is arguing that they should go. I guess my main point here is: it’s best to describe the law in terms of its necessity. Is it necessary or useful to require pre-notification/approval of all mass meetings of people (regardless of the purpose even)? I think it might be useful. Is it necessary to have SOME regulations in place for mass meeting (like forbidding them around daycare facilities, for an obvious example)? I think definitely yes. Now, if a government was actually oppressive and unrepresentative of people, and the only way to protest was to do it at a daycare facility - I would support it, but such circumstances are extreme and at that point permits and approval is irrelevant: if the government spits on people, you can spit at its permits.
