In the longterm it's theoretically possibly, in the short term (in human lifetimes) we'll die on this planet trying to make it happen elsewhere. To colonize another planet will take a lots of terraforming. Terraforming takes tons of energy in manufacturing, transportation, and sustainability. Those resources will have to be mined from earth, transported to another planet, and installed there until a colony is sustainable.
A bit of history. The American Revolution was initiated by the Stamp Act. The Stamp Act was initiated because the UK government treasury was being drained by trying to sustain a distant colony. They assumed, wrongly, the colonists would help pay for the ships, army, and resources they were being subsidized. The French revolution began out of King Louis XVI draining the French treasury to support the American revolution. When famine hit and he didn't have the resources to feed his people, CHOP!
So to get a space based colony running you're going to need to convince a whole lot of people that things are going to suck for a while but the payoff is generations away. I don't see that happening in todays climate.
I think the series The Expanse gets space colonization mostly right. The Belters have it hard because space. Terrans have it hard because Earth is dying.
