Buzz Aldrin has said that NASA should stop spending $3.5 billion per year on the International Space Station and relinquish low Earth orbit activities to private companies, such as SpaceX, Orbital ATK, Boeing, Bigelow Aerospace, and Axiom Space. This would allow for the funding of "cyclers" to enable a base on the moon and eventually a permanent presence on Mars:

Establishing private outposts in LEO is just the first step in Aldrin's plan for Mars colonization, which depends heavily on "cyclers" — spacecraft that move continuously between two cosmic destinations, efficiently delivering people and cargo back and forth. "The foundation of human transportation is the cycler," the 87-year-old former astronaut said. "Very rugged, so it'll last 30 years or so; no external moving parts."
Step two involves the international spaceflight community coming together to build cyclers that ply cislunar space, taking people on trips to the moon and back. Such spacecraft, and the activities they enable, would allow the construction of a crewed lunar base, where humanity could learn and test the techniques required for Mars colonization, such as how to manufacture propellant from local resources, Aldrin said. Then would come Earth-Mars cyclers, which Aldrin described as "an evolutionary development" of the prior cyclers.
[...] NASA officials have repeatedly said that the ISS is a key part of the agency's "Journey to Mars" vision, which aims to get astronauts to the vicinity of the Red Planet sometime in the 2030s.
Is the ISS a key part of the "Journey to Mars" or a key roadblock?

I sometimes wonder if we just sold Mars to some corporations if we wouldn't be there a lot faster then whatever the current projection is. That said Mars has been there for a really long time, I'm sure it will still be there in a century or whatever it will take for us to get there -- get there in the sense that its a regular thing and not just us sending some one-way-mission and then never going there again for another 40 years or so like we did with the moon. We have not been there since 1972 if I'm not wrong (not counting secret military projects and/or meetings with the alien overlords if such things happen).
