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)

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.
