It is 100% inconvenience, and if there’s one thing that can not be tolerated in these times, is any sort of inconvenience.
Well that's kind of the point - protesters don't have the power to change anything based on physical inconvenience. The inconvenience is merely a PR effort because protesters don't have any more effective form of of PR - if people are famous/wealthy/powerful/etc. they have better forms of PR available.
The problem with some styles of protest is that they're asymmetrical in terms of damage. A relatively small number of people who get worked up enough can congregate in one location and indefinitely shut down the operations of a person/group/organization/government. At some point the legitimate governing body needs to enforce the functioning of society, or they'll lose the mandate to govern.
Case in point: look what happened in Israel when the Abraham Accords were signed, Hamas decided to go for the "nuclear" option.
