It is clear that you can travel into the distant future if you

You can travel into the future by simply sitting in your
armchair.

And ignoring the word "distant."

How distant is distant? If you go to sleep and then wake up, was the
travel instantaneous? If your bones are still in the chair a million
years from now, is your journey forward "distant"?

The point being, we all travel forward in time. That introduces no
causality problems.
