You certainly can occupy private property as a protest, if you get arrested afterwards is immaterial to the fact that you can indeed do the as a protest.

People throw pies at politicians faces as a protest and they're often arrested afterwards for assault, but it doesn't mean they can't do it.

You’re obtusely mistaking the word “can” to mean “physically able” when in this context it clearly means “is permissible.”

Can you murder someone? Even if you are physically capable of pulling a trigger, I think you know damn well that’s not what anyone means.

Am I using the word in that way?

Sit-ins are an old protest tactic. They were used during the civil rights movement, in private property. They were used during labour protest, in private property. They have repeatedly been successful at achieving the protestors ends. They have repeatedly, in hindsight, been viewed in a favorable light and broadly seen as permissible. They were frequently, at the time, viewed as illegitimate and impermissible. Of course, there were other sit-ins which failed and were very much unpopular and were unjustified.

That's some 'Comaneci perfect 10' level semantic gymnastics. Honestly I'm impressed.
