In a democracy, you can participate in our system and vote to have it changed, though. And that’s the effective way to address these issues.
The point is that the "right way"--the way that is sanctioned by the system--is deliberately hobbled by many people in positions of power, to be completely ineffective. So you may well have to push the bounds of the system to actually address these issues.

If you want to change how a business operates, you can arrange a boycott as well. Companies take the threat of losing significant amounts of money very seriously.
If you honestly think that this type of action should be legal, then by all means, go convince our government to make it so. But I don’t think you are considering the long-term consequences such a change would have.
