The I2P netDB isn’t a single dumpable list like you’re suggesting

I am well aware of the design and structure, you mentioned I said some things there that I clearly didn't say.

So yes, you can suspect I2P traffic if you really try, but fingerprinting and wholesale blocking don’t scale

If I2P is outlawed, and there's a strong possibility we'll see that in our lives, and ISP's are told if they let unchecked traffic through they're responsible for legal ramifications. They'll run enough nodes in enough places and terminate enough end user accounts (at the very least in the US) to make people not want to run it.

I don't care if you can't DPI it. If it's on their network, and they start running peers, they will be able to root people out, not everyone, but they don't need everyone. If the ISP's share their data with each other, making that map isn't all that hard.

The floodfills can be secure and ephemeral AF, but P2P traffic, even packaged through garlic still passes through points that can be seen.

The whole design is supersmart, and from a legal stand point it's solid. But when we lose protections of beyond a reasonable doubt become stripped, they'll tear that network apart user by user until no one wants to chance running it.
