Many of the immigration restrictions in america started around the time the first welfare programs were introduced. Before that, it was a bit of a free for all. I don't know if the same pattern holds anywhere else, but I'm suspicious that might not be a coincidence.
But regardless if that is right or not, siblings have pointed out that open borders are in fact common-place in many parts of the world today, e.g. EU and USA’s internal borders are open. And (as sibling has also pointed out) historic precedent or existing examples are not necessary to justify any belief. Abolishing slavery did not need a historic precedent, neither did gay rights, and theoretically neither does open borders.
