Which is not an acceptable answer, at least from the perspective of an offline node accepting payment. People will exploit it by paying an offline vendor, taking the goods then rushing online to create a doublespend which reverts the transaction.

So offline vendors will never accept it as payment, and the entire feature is useless.

IOTA seems filled to brim with red flags to me, but where does the expectation come from that you can use electronic money offline?

You can't do it with credit cards, people will generate fake numbers.

You can't do it with bitcoin, someone can double spend with a higher fee.

Who said anything about offline nodes accepting payments? I wouldn’t expect transactions to even be remotely possible offline.

In my understanding, the ability to make transactions on a sub-tangle while not connected to the main network is sold as one of the main advantages by the IOTA creators.
