So, please let me paraphrase:
You want EVERYONE to have to put their location up so that those FEW looking at an unmonitored Sales area can save themselves the effort of contacting the Seller to find out where they are?
Good luck with that proposal.
As for the regional rationale, how is putting your location going to be anywhere near as useful compared to a thread title such as "LF catch-up for [insert region here]"? If you're contemplating somehow searching for local members and then sending them PMs, I'm going to call spam. Unsolicited contact.
