I think that fundamentally people are conservative when it comes to new technology. That's all.

If the rocket puts a car into space, we have the ability to put a car into space. If the rocket lands and is reusable and cheap, we have that ability. If we send colonists to mars, we can send colonists to mars.

Until it's done, people won't worry about it or incorporate it into their worldview. Short of offering to help, what's the point in worrying about it until there's something new that I can do? There are way too many things to worry about them all, I just care when a new thing is actually available.

Mars colonization isn't a worry, it's a hope.
