That's my point

I wouldn't say infinity is undefined. You just can't expect it to behave like the numbers do. It wasn't brought up properly.

I've certainly seen applications for such systems, but you have to recognize, if you allow this sort of operation, there is a price to pay.

I've seen various totally rigourous systems of mathematics that include conventions about what 0 times infinity is, or things like that. You just have to recognize that infinity can't be manipulated like a number, and make sure the additional rules you introduce to manipulate infinity are consistent with themselves and the existing rules.
