Default More chemical rocket insanity

Why develop a technology to make fuel in space when the
whole concept of using chemical rockets to go to the planets
(with humans onboard) is terribly flawed, too expensive, too
slow, too backward?

We use chemical rockets for human spaceflight because no other viable
alternative currently exists. Ion, solar wind, space elevators, and
other methods are being investigated (ESA's SMART-1 to Luna, NASA and
the Planetary Society's work on solar sails, etc). Of the existing set
of alternatives, only ion drives are currently rated as space worthy.
AND, due to ion drive's low thrust, it is not yet practical for human
spaceflight; while a chemical rocket takes ~7-8 months to get to Mars,
an ion rocket could take YEARS - far too long to ask our brave
astronauts to wait for planet-fall!

Yes, we would like starship-like capabilities, like, yesterday!
Enterprise is not yet here, I'm afraid.
