I don't see a problem with it. A lot of the communities around here are the same way (the fine amounts very). And they actually do enforce them, via the recycling trucks. The drivers write down house numbers where one or more recycling can is not present on recycling days. If you don't recycle - consider yourself fined.
What if you're single, living on your own, and don't have much trash to begin with?
The plastic bags at stores is insane. I always take paper whenever I can. Last month, our village gave everyone one of those new recycling bins that has the wheels and lid built in. Pretty fancy, and it's free too.
And although I never turn off my computers or printers, I set them so that they go to sleep after 15 minutes of inactivity.
One thing that I absolutely refuse to use, however, are those god awful CFL bulbs. They are more hazardous to the environment than incandescent bulbs.
