I disagree that voting has become meaningless. The issue is that young people think and feel that voting is meaningless. Thus politicians don't really have to pay attention to what young people think or want.
(You don't vote, you don't count.)
If you don't vote, your peers don't vote. You transfer your power to other people. Think of NRA. It is a small relatively movement. But if they say to their members go vote X, 100% of them are voting X. This conviction makes a difference. Even if they have 200 votes say, those 200 people are going to make sure everyone around them is going to vote appropriately. And the numbers stack. Also, as usual in the U.S. call your representatives, create a group and take legal action through courts, etc.
You have other tools in your belt too, which you mention. These are the "oh shit". But you wouldn't want 20 years from now, to have to use them, or go to jail for using them, because they were illegal.
