What? If the majority of people support your desire to not pay taxes, a _functioning_ democratic society would quickly pass the "2022 csee tax exemption bill". While you'd probably start bleeding support for your cause if you shut down all international trade, basically any measures are justified at that point because the government is no longer being responsive to the will of the people. If the government is allowed to go ahead and arrest people for that, that's the literal definition authoritarianism.

If the majority does NOT support your demand, then yes your right to protest can be limited by others right to go about their lives. The more disruptive your protest, the less room there is to tolerate it. But a simple threshold of harm as you argued for is not the right test for this. Harm and public support. If 40% of people support your cause, a democratic society would not enact that cause - but it would tolerate more economic harm than a cause supported by 0.4% of the people.
