But what is economy anyway ? Recent events showed us that money was not economy, you can print as much as you want and 'helicopter' it.

It is more about the resources, do we have enough of it to make it possible for regular people to travel to space ? Probably not on earth, so let's build mega factories on the Moon. You might argue it's not possible or feasible for some physic reasons, so let's find a solution. But not money, money does not exist, it's made up.

The purpose of humanity as I see it is not to go smoothly and safely, to be able to go without troubles to a final destination (that does not exist). I say buckle up and let's do it! As Billy said you need to be solution oriented.
