So the good news is that a majority of the Supreme Court understands that “international law” is conceptual and voluntary.

Very true. The question is. . .don't we want our citizens to have access to the U.S. consultate if they are arrested in a foreign country? If the answer is no, then there is no problem. If the answer is yes, then this decision is an issue.

I’m not too worried about it, treaty or no treaty. Any nation that denies a US citizen access to a US consulate will no longer be visited by US citizens. It would be the end of their tourism industry and business contacts, and they know it.

The answer is: I really don't give a damn. Any U.S. citizen who travels in a foreign country is putting himself/herself at the mercy of whatever legal process (or lack thereof) prevails in that country.
