$7k/kg by Falcon Heavy pricing. Would you rather a different launch system?
Have you been paying attention? The proposal is not to launch DIRECTLY from Earth. The word you don't seem to understand is DIRECTLY.
Not really. But the problem is your "lowering prices" standards involves having to send things into to an entirely different gravity well (consumables), and landed propulsively, so that other different things can then be launched from said gravity well.
What? The problem is no one has made a vehicle large enough to launch a manned Mars vehicle. No one. It's not about "lowering" standards. It's about practical limits.
Your proposal, absolutely.
False: It's not my proposal. Experts like at MIT say it's the est option.
From Earth, there are no diminishing returns whatsoever. Just the opposite - the more you launch, the cheaper it gets per kg.
Er? Are you insane? There are always diminishing returns. So the ISS was launched at once will all modules intact or was it built over decades? Why was that? Because no one can build a rocket large enough.
One: completely and utterly false. There are a huge number of different proposals for this, all of them technologically feasible.
Two: your counterproposal involves doing the same for the moon, and then doing constant resupply so that they can build things that require an entire industrial base there. It's an absurdity.
Again, not my proposal
It does not require a huge infrastructure but it does require infrastructure. The alternative is using Earth to refuel at the high cost of LEO orbit costs.
Incorrect, and an absurd statement to make. The "Journey To Mars" program is the core of NASA's focus. (If it wasn't, nobody would ever put MOXIE on Mars 2020. ;) )
Do we have a manned space vehicle ready for Mars? It is in the planning stages? By YOUR LOGIC, the mission to Mars doesn't exist either.
