They can where I live. While I might “own” the land, I’m in Canada and there’s a very specific and technical legal definition, I never “own” anything. The land is owned by the crown, and we lowly peons get to “buy” (or lease in perpetuity for a one time set cost, plus property taxes every year) the land we live on.

The Crown, and by extension, the government acting on behalf of the crown, can do whatever the fuck they want, including telling you what you can, and cannot do with your land, and whether you can turn it into a trash heap.

Many other places are the same, though, not as technically/legally screwed; I don’t have to look any further than city zoning to know that similar (in effect, not implementation) rules exist for everyone. Zoning means you can’t just turn your plot of land into an industrial manufacturing operation because you feel like it. That’s the government telling you what you can (or cannot) do with your property. There’s plenty more examples and rules that limit people’s freedoms as to what they can do with “their” property, if you do any research at all.

Don’t be such a spoon.
