satellite refueling and menstruation

It's been said multiple times now that if someone doesn't like their
colony, they can just pack up and leave. I'm hearing a lot of this in
America today ("If you don't like it, LEAVE!") But people certainly
don't want someone else to tell them that they have no other choice
but to leave the only home they've ever had. The first few decades of
space settlement will likely be strictly controlled by Earth
governments, and many will likely still be under the suzerainty of
Earth for sometime. But after some incalculable amount of time,
settlements will move further out and become more isolated. It is
precisely this isolation which will allow radical governments to
develop. Leaving one isolated colony for another may not be so easy,
especially for an outcast with little money. Also, border control on
a space station would be a pretty simple matter. Sort of a billion
mile thick Berlin wall. Escape would be difficult. Additionally, many
stations will not want to accept refugees from wacko colonies, since
they will already have their own population pressures. Being much
smaller than Earth countries, they will not be able to easily absorb
homeless/jobless people. Earth will probably accept refugees, but
societies living months/years away will be unable to send them.

It seems that due to distance we will have little choice but to
ignore totalitarianism and human rights abuses on far flung
settlements. I only hope that by doing so, we are not creating a
cancer that comes back to haunt us in a thousand years.
