True, but time is also a nearly unlimited resource. I suppose the Universe may eventually suffer heat death. But again, these fundamental limits won't matter for billions of years.
Jeez, this discussion is silly but what the heck.
Time is not an unlimited resource. At all. Especially if you travel interstellar space at relativistic speed. Your proper time will tell you that you've spent a year, but the solar system you left may have seen centuries pass away.
Cosmologists now think the future of the universe will be a deep freeze. So if you spend too much time gathering stuff in the universe, you'll end up in an almost empty, deadly cold universe.
