Well than it’s not working, because microbial action causes the smell.

I'm no scientist, but it seems to turn my food scraps into dirt without smelling bad.

It’s a garbage can, what harm can come from someone using it?

The harm is that I can no longer quietly enjoy my yard. Because it smells like poop.

And if you don’t want it touched, put it in your backyard or lock it.

I have to take the trash to the curb in order for it to be picked up. I leave for work before they pick it up, so it's out all day. During that time, it racks up 3-5 dog poops, guaranteed.

Are people not free to walk up to your house and touch your doorbell?

You're being obtuse. A doorbell is intended to be used by the public.

If I had an apple tree in my front yard that’s not fenced, yes the neighborhood could freely help themselves, obviously a bike is an entirely different situation, and using it as an example is fallacious.

The only thing I can think of is that you must not live in a city. We get a lot of foot traffic here from people who I haven't met and probably never will. If they all felt entitled to pick from my imaginary apple tree, it would be bare in a week.
