It will be interesting to see what happens here if it gets more developed in the coming years. Everything is fine when these uses all fly under the radar as people just go about making a living and improving their situation as best they know (incrementally).

When that happens, the "rule book" comes out and conflict ensues... This certainly happens everywhere.
