I think this is both trivially true an irrelevant. The fastest car that we can build is only limited by the speed of light, but we can’t really make cars that fast for a vast number of reasons that I am too lazy to spell out. I am not interested in a theoretical world where if we run out of phosphorus on Earth we just make new atoms using fusion or we make rockets to mine distant asteroids. I’m interested in Earth on the 21st century, where if you interrupt the transit of boats in the Black Sea people in Africa die of hunger. We are, in fact limited in the amount of food we can produce, and although we could increase the amount of the Earth surface devoted to crops, that comes at a high ecological cost. Same thing for many other resources.
