When you go outdoors, people are free to look at you, but that does not mean (as a rule) they can shoot pictures of you without your permission. Same principle can be applied to your property. Like, if a stalker takes a photo of your window hourly or keeps track of your car – that could be treated as infringement of privacy. If a door is unlocked, that does not mean you're allowed to trespass.

That's not generally true in the United States. If you are on public property, you can take a photo of anything or anyone you can see. You do not need their permission.

There may be local laws that restrict this, but they are not the common case.

Anywhere is literally viewable from space. Some radiation types also give information to sats about what happens indoors. So your question is basically:

  Do you think you have a reasonable expectation of privacy anywhere ?

Reading it like this, is this really the world you want to promote? Or is privacy being only obtainable in bunkers a few km below the surface an acceptable compromise?

I'm not aware of any technology as of yet that can see activity through a thick and insulated roof from low earth orbit or even a few thousand feet up for that matter. But I could be wrong.

I remember seeing a (dead tree) newspaper article a few years ago about the police using sat images to detect potential cannabis plantages by the heat radiating from the building.

Sorry, can't seem to find it on the net after a quick DDG

I think they were using plain old thermal imaging cameras (not satellites). However, Kyllo v United States now requires a warrant for that.

Yes, that would make sense because lots of grow lights can cause significant heat. I don't think heat technology could see individual people through a roof though.

Thermal imaging is easy from a helicopter or survey aircraft, that's enough to find likely locations for plantages.
