So you mean secondary use 1. as persistent storage (e.g. fake Multisig) 2. as publication medium (e.g. for time-stamping) 3. as general smart contract (e.g. time-locks) …? I particularly like the time-locks and wouldn’t consider these spam even if it means we carry them around.

I guess lightning channels are spam then huh?

So the message in bitcoins first block made it a spam and it shouldn't be mined today by your standards? Interesting. There have been inscriptions literally since the first block....

Lightning is cash too

Wrong

In your opinion... That's the point. Spam, cash, VALUE is subjective. Satoshi already solved the spam problem with proof of work. Also, I would agree, lightning Bitcoin is mostly used as cash.
