Nobody is “asked” to put up a fence by city or county government. They are told to if required to by some ordinance. Usually if there is a pool or problem with a dog getting loose all the time. You can be sure the type of fence permitted (or required for a pool) is clearly stated. If the neighbors asked that doesn’t change having to put up one made of allowable materials. For the most part people don’t ask neighbors to fence off their property unless there is a nuisance like a big pile of crap they are tired of looking at. The tire fence people are the sort that keep code-enforcement divisions funded and justified.
If you don't like lookin' at the neighbors, put up your own fence so you don't have to look at them...
