The more you heat Mars, the more atmospheret will boil off into space!

A Martian atmosphere of two Earth equivalent surface pressures would be
stable for a geological time period. Like 10 million years. Long enough for
humanity to set up home, complete terraforming, nuke ourselves back into the
stone age, redevelop technology, colonize the solar system, evolving into a
higher lifeform, move onto the Oort, develop FTL and head off to
Andromeadia. Boil-off into space is irrelevant unless you're talking about a
much more lumiscant sun and 5-billion year time periods.

Really??? And you have the Physics of that worked out???

A "side of the envelope calculation" (even more cursory than back of
the envelope), gives about 2600 comets each about 20 Km diameter to
raise the atmospheric pressure from .01 earth to .1 earth. This uses
only the material of the comet (assumed .2 gm/cm3) and does not
account for any greenhouse effect that will cause more CO2 to go into
the Mars atmosphere. It might be considerably fewer. It also does
not account for CO2 and water vapor produced by cometary impact.
