Any idea if there is an argument for moving it if it obstructs sidewalk traffic, whether or not it sustains damage in the process?

I feel like you can't just leave a washing machine blocking the sidewalk unattended and sue anyone who scratches it while moving it? (IANAL)

If it obstructs the sidewalk and isn't moving, you can almost certainly move it. You should act in good faith and try to do so in a non-damaging manner if you want to avoid vandalism charges.

If it's moving? You should just wait for it to go obstruct some other part of the sidewalk.

Just turn it upside down then. At best some “Good Samaritan” turns it right side up at some point but the food arrives late, cold, and spilled all over the inside of the robot.

Or just push for better regulation instead of resorting to childish vandalism?

More childish than the process of getting new regulations against big-tech approved in local government? I’d say it’s a tie, at best.

Was the Boston Tea Party childish vandalism or heroic patriotism? Only history gets to decide how the actions of disobedience are ultimately judged.

I suspect that as a rule, anyone comparing their own activities to things like the Boston Tea Party is pretty much always wrong.

Cross your fingers and hope there's less than $300 worth of food in there.
