That still doesn't solve the problem of Mars' inadequate gravity.

Where is the proof that the reduced Mars gravity is a problem at all?

The only solid evidence we have to go by is rather limited (maximum one
year) exposure to ZERO gravity for a very few individuals.
Extrapolating ZERO gravity research to apply to partial gravity is
fraught many questionable assumptions. For real people dealing with
real life on Mars over many generations, .38 G might logically prove to
be an advantage that ultimately extends human longevity. We simply have
no way of knowing because we have no way of running the experiment.
