> One idiot or provocateur in a sea of tens of thousands does not override the 99%.
When the blockade is significantly funded from outside the country the policies are supposed to be about [0], when effective mechanics of the protest aren't merely speech but crippling trade, when the stated substance is basically claiming the privilege of unrestrained motion across international borders without regard to vaccination status, even if it were true that "one idiot or provocateur in a sea of tens of thousands" were engaging in fundamentally unacceptable (e.g. nazi) performance, there's still be plenty of reasons for sensible and restrained government authorities to intervene.
> This precedent being set is a dictator's dream
Which precedent? That authorities might use authority to stop trade disruption?
Seizure of property from people involved in that disruption? Bigger and far more routine problems in terms of civil forfeiture.
Needing to be vaccinated to cross a border? You may want to look at precedents established over the last century or two and ask yourself why the totalitarian catastrophe you seem to be imagining has only crossed some kind of threshold now, almost as if it isn't coming.
