Yes, but in a world of 65000 users you're left with a lot less data. It may be enough for your purpose in which case that's great. For smaller areas it probably works quite well, but I'm fairly sure it'll hit a scalability problem. With OSM as a whole we rely on there being more good guys than bad guys, and that's generally worked so far, but you do have that instability problem in that it can take a while for errors to be detected and corrected. The subtle vandalism is hard to spot because it looks genuine. You only determine it isn't genuine with local knowledge or on the ground observations. That means you can't trust anything until it's been checked out by a trusted member and the more people you bring in as members to hit your coverage goals, the more chance you get compromised and start letting in lower quality data. How much of this is actually a problem depends a lot on what you are actually trying to achieve.
