That's a great idea. Make the stores do that and all you'll be able to buy is fake plants and little bubbling treasure chests. I don't think it's the LFS's problem if it dies because you can't take care of it. That's YOUR responsibility. Should Ford make sure you can drive a V8 without crashing before selling you a Falcon? No, it's your responsibility. They can tell you it's hard, but if you choose to buy it why should they replace it when you kill it?
But, yes, I agree, they shouldn't bring in anything that has a very low chance of survival. Of course, that's also why a lot of people complain about not being able to get a lot of SPS I think. Because most people don't have the equipment for them and they die.
