Marie Mott is quoted as asking, “So you’re telling me blocking a road instills fear in the community?” Apparently she was seeking the approval of her peers; for a more objective answer, she should've asked 'the community' instead. You know, the community -- those working, taxpaying folks who actually pay for and build the roads, public buildings, private homes, etc.
The basic answer to her question is, yes, it does. Such antisocial and illegal activity produces many immediate results in those you inconvenience and endanger, results including confusion, impatience, anger, fear, and an urgent desire to escape before things get worse.
Properly raised children learn, among many other things, not to play in the streets, and certainly not to frighten their elders. They are also taught that actions have consequences for everyone involved.
We old folks have many unavoidable, uncomfortable, and unpleasant personal problems, including weak hearts, weak stomachs, weak bladders, high blood pressure, anxiety, and seriously altered reaction times. Sudden surprises and shocks can cause unfortunate results that surprise even us. Getting 'scared to death' ain't a funny notion when you're as old as we are; it don't take much to finish the job! And, with all due respect, most of us really don't have a lot of time left to waste in anybody's deliberate traffic jam, either.
Well, she asked.
