Right on. I can't remember who brought up this idea, but it went something like this: imagine if Steemit's incentive system applied to everything in life. So when someone stopped to help you with a flat tyre, you could upvote them, or if they give you good advice, or even help protect you or return your property, as you're describing.

I remembered a couple of times where I returned people's wallets or IDs when I found them on the street. I didn't expect any reward for it, but if we want to live in a really great society, these are the kinds of things which should be rewarded. I can't wait until someone figures out how to do that in a way which is as easy as upvoting a Steemit post.
