In economics, we call something a “good” if utility is increasing in t—the quantity of it consumed—and utility functions are often unbounded
I don’t think that’s true. Modern economists say utility is increasing in t _at the relevant margins_. There is no claim that it’s unbounded or that it doesn’t become negative utility at some future time or quantity.
Yes, agree with you! I was more classifying the t that OP was asking about than providing a definition, but wording was somewhat unclear. Have edited the original comment.
