Assembly amongst all groups simultaneously isn’t possible with humans who are not bifurcating bosons.
Just because you used a word in a sentence doesn't make it so.
> A team assembling on the playground that doesn’t pick all the friends who want to play together has prevented the friends from assembling.
They haven't prevented anything. Just because a team assembled, does not exclude others from being there.
They can exclude, of course, but that has nothing to do with the assembly.

> When you refer to rights of assembly or restrictions on assembly, you are referring to the legal right that people have to gather together
It's the gathering thats the assembly, not the exclusion. You just made that up.
