A community "maker space" would require careful curation of community members to be viable. Even if everyone were honest and conscientious. It's so hard to find the right tool or material at the right time in my own shop, it would be many times worse if I shared the shop with the neighborhood. Sure it's a long, hard, expensive trudge to accumulate your own tools, but at least it gives you a good chance of having the use of them when you need them.
