The reason lightning fixes it is because it bypasses the blockchain, defating the purpose of a cryptocurrency's security in the first place. Also, this video doesn't even seem to mention Monero (checking the transcript) and this video is 6 years old. Monero has changed a huge amount in 6 years
> you're claiming there's some determalistic (or even some general probabilist method) that undermines monero privacy?
I'm not claiming that. But I think that's what this privacy expert claims: https://www.youtube.com/watch?v=9s3EbSKDA3o
> so what's your fucking problem?
My problem is that monero people claim it is private while permanently publishing massive amounts of info about each of their transactions -- something lightning fixes, even though a few monero influencers like to ignore that.

And by "fix", I mean it just holds the transactions privately until the channel is closed (so the funds are actually moved). Before that you are just moving a bunch of IOUs around
