It's not limitless, you still need fuel. Especially tritium doesn't really occur naturally because of its extremely short half-life, current plans for ITER involve breeding tritium from lithium in the fusion reactor. The closest to limitless power we have is PV.

Tritium is a convenience, not a necessity. If researchers manage to build a functional fusion reactor which captures the energy, we can find substitutes.

A reactor that produces enough of its own fuel.... It's starting to sound like a perpetual motion machine.

Read again, there are plans to use lithium instead of tritium, still limited.
