Do people care this much about this specific porn site that they are willing to upend global infrastructure? Principles don't make precedent, it takes money and actual interest to do that.

The latent ability of the United States to shut off some specific domain within a TLD is never going to cause people at large to say "We'll make our own .com with blackjack and hookers!"

In this hypothetical new system, other DNS roots would exist - and for practicality's sake, wouldn't collide with the "old Internet." Nobody is reissuing .coms, they will pick some new TLD or system entirely.. this today is known as a "ccTLD." Are people interested enough in true sovereignty beyond what ccTLDs offer? What does that even look like?

Why do most businesses enjoying .com domains today want to move to your system of control? Nothing can be truly "decentralized" any more than the DNS of today is: countries effectively opt in one way or another - the internet is a cooperative system, much like international diplomacy.

"They came for the X and I said nothing"

(XXX in this case)

It's the precedent it sets, and especially with the ... sensitivity ... in the US at the moment around 'opinions on things', this feels like it could be the first pebble of an avalanche.
