Would not that imply they may require us to provide xpubs to proof existence of funds?

Correct me if I am wrong, but if it is the case collecting xpubs from users does not sound good.
It doesn't sound good at all, and I wouldn't suggest anyone to connect all their coins and accounts on ledger wallet with this new card, that is if they care about privacy at all.
4% cashback in XLM, and if you use USDC to fund it, since it's a 'stablecoin', there are no tax implications.
Are you paying those crazy high ethereum transaction fees for every transaction you make with your card?
I think it's not so smart at all to use something like this when transaction fees can go over $100, and ''stable'' don't sound so stable anymore.
This is horrendous.
The whole point of a hardware wallet is to keep your keys and your coins in your control, away from centralized services, away from custodial services, away from exchanges.
You know that ledger hardware wallet will also integrate with coinbase and ithink that is even worse than connecting it to debit card.
It also sounds like the dumbest and most insecure thing ever

Yeah it is dumbest thing ever, and I think that majority of general crypto population is very exited about this feature, but we know from history that majority herd is never right or smart
