Your example is akin to there being a very clear "No Jaywalking sign", jaywalking anyways because you see no traffic/others doing it, having a cop hit you with a ticket, and then complaining that the cop is abusing his power. No, you just got caught; and are whining.
Society has decided they don't want people doing that. If you don't like it, convince enough of your peers to change it; or accept that the society you're in doesn't agree with you. Welcome to democracy.
Exactly, jaywalking is also a made up crime that benefits some (car users) at the expense of everyone else. Just like copyright it is a bad deal for society and should be ignored whenever possible. Reclaim pedestrian spaces AND reclaim your culture!
