I liked this on Lightning and money transmission: https://medium.com/@ekladous/are-bitcoin-lightning-nodes-money-transmitters-24cc5f1a38c6
If you run a Lightning node, you are obviously running software that helps people to transmit money. However, the transmitter can't steal the money, and that article gives multiple other reasons why Lightning is expected to be safe from the regs
But I'm still a bit nervous about this. Regulators might try to cause trouble for Lightning nodes
