Don't get triggered, I just pointed to the parts you got wrong.
Again, every single monero node is collecting all the network information and will keep it as long as the network is running.
There's NOT such a thing on #Bitcoin #LN. There MIGHT be someone collecting and keeping information for long time, but NOT EVERYONE. Please confirm you do understand this point.
LN isn't just Bitcoin and it might one day be implemented into monero too because AFAIK, it cannot scale without L2.
