Absolutely not.

At the VERY least, the road blockers should be fined the cost they caused to society.

Block Golden gate bridge for 1h30min for 10,000 people (Avg salary $50/h)? That will be 1.5 * 10,000 * 50 = $750,000 damage.

Well, if they caused you any specific loss nothing prevents you from suing them in civil court like in any other situation when somebody causes you a specific loss. That though is a completely different thing from criminal prosecution.
