Sure. And holodeck with replicators are right around the corner. Do you know how science works? Do you think it's just throwing money at people in lab coats until they give you what you want?

Having a plan is very different from being able to even test its viability, let alone execute it. Right now delivering relatively small inanimate objects to Mars intact is a gamble. And it's telling that the often cited greatest hope of human endeavor in space is a company owned by a mentally unstable conman.

Do they only sell gravity generators at the fancy store? Or are you talking about the costs in human health and lives? We are maybe closing in on having a workable solution to the radiation problem. We are nowhere near solving gravity and nutrition problems.

I don't want to sound pessimistic, but suggesting that humans will full-time live away from Earth is on the level of "nuclear reactor in every car".
