In the cases mentioned, you don't have the right. Local law enforcement are just not enforcing the laws. The question you should ask is why, and who benefits from adding chaos.

In the recent San Francisco area bridge blockages, they would throw their car keys into the water to make it harder to move their vehicles blocking the lanes, and have their hands locked to one another inside of metal tubes resistant to easily separating them.
