No, it isn't. You have freedom from restraint, but you never have the right to a specific route at a specific time (excepting corner cases where there is only one possible route out of a place, and blocking it would be de facto imprisonment).

The blockings of roads by the Last Generation are those „corner cases“, because of how they are executed: without a warning a road in front of you is closed and you are stuck. It would be easier to understand if they had left an emergency lane and gave a notice in advance.

What a bizarre thought. Fortunately nearly everybody and every country disagrees with you.

Article 13 of the Universal Declaration of Human Rights:

* Everyone has the right to freedom of movement and residence within the borders of each state.

* Everyone has the right to leave any country, including his own, and to return to his country.

...this is in reference to protestors blocking a road. Are you seriously trying to say that temporarily blocking a road infringes others' right of emigration?

The first part is clearly not about emigration.
