An Infinite Number of Potentials Doesn't Exist

According to Thomistic metaphysics a potential can't exist on its own. Since potentials don't have the same kind of existence as actualized entities like hotel rooms then there may not be any problem with an actually infinite number of them existing. And it seems plausible that no actual infinite number of potentials even exist given the limited natures of created finite things. So to summarize this objection doesn't work against people who think actual infinites can exist.
