Euthanized is better than a dump with thousands of animals that can't be cared for because the place is going bankrupt.
Here's an example for comparison:
What if they were to pass a law that said because you own a reptile you are part of the community, and you should be required to pay for the upkeep of those animals whose owners abandoned them. It would only come to a few thousand a month, and they could deduct it directly from your pay.
Suddenly it doesn't seem like such a good idea does it?
Laws are dangerous things. They have lives of their own and can ruin a community as easily as they can save it.
