Monero's transactions are larger than Bitcoin's because it is actually private and fungible***

You're talking about a future hypothetical that may never even happen (slow adoption + moore's law = scalable). But this also says nothing about the reality of total blockchain size today. Running a Monero node requires less resources.

Lightning is broken tech that doesn't translate all properties of Bitcoin that make it great. That is why 95%+ use custodial wallets like WoS. And the worst part is it still can't even scale by it's own metric.

Network effects also apply to Monero. King in the privacy coin category. No competition in sight.

If you think Monero is complicated to use, try using lightning in a sovereign manner:

need capacity to recieve,

can't send modestly large amounts,

both parties must be online to transact,

must run an additional ln node,

can be rugged if your node isn't active,

can be force closed onto the base chain against your will and pay higher tx fees.

When was the last time you took advantage of Bitcoin's transparent simple math?

Or do you just run a node and sometimes have a command spit a number back at you? Exactly like any Monero user.

Finding an inflation bug after it's exploited doesn't help.
