Lightning is supposed to allow ONE person to open a lightning channel and leave it open for months if not years... resulting in ONE maybe TWO on-chain transactions and thousands of Lightning transactions for that individual.

This keeps blocksizes relatively small, keeps fees sustainable for miners, and results in Lightning transactions which are instant, cheap, and sustainable for as many people as possible.

Lightning works, and in my experience does a great job increasing the 'privacy' of Bitcoin while making transactions cheap and instantaneous.

So if there is so little 'merchant adoption' and so little "onchain activity" to *open those Lightning channels...

What is the reason for this?
