The reason why we never meet time travelers is because our civilization ends before the technology can come to fruition.
Sort of similar to the Great Filter theory, but applied to time travel technology.

The reason it doesn’t disprove it is because the assumption “time travel works” is really just saying, if we ignore some basic rules of physics, what happens to what’s left? It’s a nonesense premise to debate what is basically nothing more than science fiction.
Could the rules we know about the universe be wrong? Absolutely! But discovering those new rules is what will answer that question. Till then, we might as well try and say Harry Potter is just quantum mechanics.
Look up Dr. Ronald L Mallett. This astrophysicist has some interesting takes on practical time travel. There's a great interview with him by Fraser Cain of Universe Today.
