Actually something with strong copyleft semantics might actually be more appropriate than MIT in this case (if we're already willing to legitimize the copyright system by having a license, which is necessary). If the argument is that everyone should be free to use whatever code however they want, then MIT lets delivers on the "however", but not the "whatever". GPL slightly limits the "however", but delivers on some of the "whatever" due to its viral nature.
