Where did I say that it should become legally mandated that MasterCard associate with anybody? Not only do I not think capitalism does/should compel them to do that, I think that capitalism explicitly doesn't compel anybody to do anything.

What I'm asking is if we as a public really want our payment processors to be making these moral judgements? That doesn't mean I think they should be compelled to do anything, but I certainly think it's cause for concern, and call for an alternative that IS willing to behave as a neutral party. I don't want the noise of what is effectively a pipe to be making arbitrary political judgements when deciding what is allowed to pass through.

Now, publicly funded banks, that's a different question. I absolutely expect neutrality within what is legal from our government institutions.
