This was your hypothetical, but it’s actually reality. Protest is protest. It’s for the whole society to decide what are valid forms of it, at every level.

That's just lawlessness.
There's not way to make up the rules as we go along, using the 'winds of the day' and what's happening on the news to determine what's a legit protest and what is not.
We do decide collectively what's what by using laws and policies. We make those, we make them clear, and then we apply them.
It seems as though you can't block traffic at a busy intersection 'because' - and so whatever the protest is today, it's not right.
We can't make up as we go along, that's chaos.
People can protest in parks, in front of city hall etc. - that works, it's peaceful and within civil framework.
You haven’t responded to my legal arguments and justifications. You are moving the goalposts and doubling down. Please keep on point or I will not have any substantial points to respond to.
