Cause you can’t actually GO anywhere on a bike. If you want to go somewhere 200 miles away for a week, it’d take a day and a half each way, minimum, and you can’t bring anything with you bigger than a backpack. It’s also physically strenuous to go literally anywhere, even the places you are allowed to go.
Saying it is good enough. It’s not unreasonable to think a regular person might be against human rights abuses. You can’t demand that citizens go support your imperialist regime just because they only indirectly show support for human life.
