I would also really like to have OP's question answered. I keep structures intact and often actually repair them and/or convert them to mini camps with basics for aesthetics. Also don't like the brown flat patch they will leave behind.

Though if it would improve performance to tear them down I definitely would for most of them. Would not mind cleaning up all those map markers for stone towers etc.

I like to erase the existence of fuling villages, so, after I eject all the tenants I tear down all the structures and clear all the farms. Then I re-seed the whole area to make it look like nothing was ever there.

The only exception is, I like to leave the roof and central column in the small round structures and leave the ground bare under it. It makes a nice place to sit in the shade on a sunny day.
