SpaceX has always mentioned sending multiple ships at once for redundancy, starting with uncrewed precursors sending supplies ahead of time.

  This is irrelevant and completely ignores the OP. We've had rockets capable of going to Mars since the 60s. More rockets do not solve the problem. Cheaper rockets do not solve the problem. Please read the article.

    The article doesn't really lay out any particularly difficult, let alone insurmountable, problems. In fact we even had plans to make it Mars before 1980 in the 60s drawn up by the exact same man who got us to the Moon. The reason we're not a massively multiplanetary species already is simply because of politics. Nixon defacto cancelled the human space program in 1972. After that we had to wait for the economy to develop to the point that private entrepreneurs could viably send us back to the stars, and that's where we are today. Had we maintained the political will though there's no real reason we wouldn't have had a colony on Mars decades ago.

    Please read my comment. More mass makes solving virtually every challenge of Mars missions far, far easier.

    Biggest problems are microgravity, radiation and lack of redundancies of various kinds. All are solvable by adding payloads.
