“When (If) we harness the technology to get there, running out of oil will be the least of our concerns.”
Very true. However, it would horrify liberals. That makes it worthwhile :-).
What really horrifies Liberals about space travel is that it opens up a whole new frontier. One that is infinite and will likely never be conquered. When new planets are being colonized, there won’t be a lot of room for Liberal fantasies, silly laws, or PC. And I’ll bet the colonists won’t like paying taxes either.
