Regarding WoS keys, they'd also be subject to analysis attacks similar to the ones you describe.
Regarding mints, WoS keys are always linked to a balance. Mint tokens require a lot of work to associate, if it's possible at all.
linked to a balance
PARTS of a balance, not necessarily a whole balance, not unlike each new minting event
Mint sees what channel sats came into and how much, it sees when they go out and how much... same thing WoS sees... the arbitrary numbers on a token or in a record are equal

OK, so do you admit that ecash isn't worse than WoS?
reply
Inherently? No
Practically? Yes
Keep in mind that the scammers and spooks aren't pushing ECash as an authentication scheme, they're pushing it as a payment spec... this is an attack on Bitcoin and thus much worse than WoS
reply
How so? It's no worse than trading pre-loaded WoS accounts.

they're pushing it as a payment spec

Then I'm not sure I understand what you mean by "payment spec".

Imagine you're at a farmers market and want to buy a thing
"Bitcoin/Lightning Accepted Here"
You go to scan the QR with your lightning wallet at the PoS, low and behold its some trash fiat spec your wallet can't pay because it's not really Lightning
Or it's extra slow because of the swap/settlement between mints
Or it fails because of all the added complexity overlaid in settlement
This adds friction, confusion, and general bifurcation of the network effect of Lightning

Have you ever tried ecash? Cashu (and I think Fedimint as well) are very well integrated with lightning. Paying invoices works like the average lightning user would expect.
