> This trend of countries declaring that everyone on the planet is under their jurisdiction if they mail something there (or respond to a network request) is bananas

I disagree.

Imagine I ban health potions in my realm. I am running a Darwininistic experiment to make my people the most resilient people of the world and I want them to succeed through survival of the fittest. I tolerate non magical medicine but anything else will pay 1000% duties or be confiscated. A merchant comes by with a delivery of health potions to "Johnathan Man". The guards point to the "Survival of the ssssttttrrroooong" banner, while the merchant throws a fit saying she has a very powerful uncle that just happens to be a known warlord. The guards laugh, close the gates and go back inside for another pushup context. Meanwhile Johnathan and the merchant complain things about jurisdiction to no one in particular.

I have no idea what you're even trying to say here. Australia is welcome to try and confiscate goods that are mailed without paying sales tax, but we both know they lack the ability to actually execute that. And their ability to do anything about digital sales is basically non-existent.

So if I'm understanding your analogy correctly, the guards can't really do anything, so the merchant and the buyer will be the ones going about their business.
