You Don't Want to Time Travel

This is like saying you don't want to travel on a highway because if you keep going in a straight line you'll end up in the bush at the first curve. Not a particular deep take - not that many time travel stories are any deeper either.

Might make an ok short story. Astronauts find a body in space dresses in a white lab coat, tie, and horn rimmed glasses. Turns out to be reclusive scientist not seen in years.

Ok, but if you could time travel in the 4th dimension while remaining static in the third, you could do some really cool things assuming you survived the initial testing.

Sell your services as a space launch platform. It should be trivial to build a program to tell you how long to time skip a space vehicle for it to be safely free floating when it comes out of the time skip, and if you can do that for less than the cost of the rocket fuel needed to launch to space, then you're golden.

You could even scour the trillions of different start/stop conditions available to you to possibly land a base on the moon fully stocked with food/air/water/power/people, and if it worked once you could also restock them as needed.

(Of course, getting back would be its own can of worms, but still)

All I'm saying is, if you use your imagination you can come up with a good use case for practically anything.
