Most people have the wrong perception that a Lightning payment is a chain of nodes transferring value to each other. In reality, when the preimage is disclosed, value is transferred directly from the payer to the payee, without going through intermediate nodes.
@ElectrumWallet In the US law, if you dig down to the core of it, it comes down to "transferring funds on behalf of the public by any and all means.". So any court case would need to clarify "transferring" and "on behalf.". If you hold a mental model of an HTLC payment as being people in a chain.

This is not about Bitcoin being money or not, of course Bitcoin is money. This is about what constitutes a "transmitter". If Bob forwards a HTLC from Alice to Carol, then Bob never holds the money for someone else.
