One thing to keep in mind that adds to the improbability of colonizing another planet is the fact that it would likely require the entire planet to work collectively towards that goal. Pooling resources and brain power and working as one, because no single country would have the money or man power to accomplish that.

Spend 5 minutes in social media and it'll be clear that we could never achieve that even if all the stuff you mentioned wasn't a factor.
