That's pretty poor marketing. Do you think Bitcoiners/Austrians would have ever started to utilise Bitcoin if it had a "pretty good" limited supply.

BTW not sure you got the pun.
"Pretty good privacy" here refers to PGP, which is an OG cypherpunk encryption tool.
I did a nice talk about Monero chain analysis at Monerokon. Things are not that straightforward as they look. Not creating a permanent record of a transaction has its benefits.
Yes, lightning was designed as a scaling solution, but it does not mean it can't have privacy as well.
