Yeah, it's totally ridiculous that I would want to live in a neighborhood of like-minded people who would want to maintain and improve their most valuable possession.
I should be totally happy putting time, money and effort into the upkeep and improvement of my plot of land while my nextdoor neighbor adds to their collection of front-yard beer cans and beater cars.
Alright, so let's remove the extreme scenario. Let's go somewhere in the middle and forget about beer cans and rustbuckets. What sort of different uses of property are you OK with your neighbors doing? What if a neighbor wants to turn his front yard into a mini orchard? Or a big garden? Or build a shed in the back without a permit? Or paint his house an unusual color? Say, he takes care of his property and isn't trashy, but just uses it differently than you do. How do you feel about that? Where's your line?
