What if I told you that it doesn´t need to scale? If its main
use case is being a store of value people will make maybe a single-digit
number of transactions per year. At these numbers the current
system works well enough.

Bitcoin´s true purpose is not facilitating online payments, credit cards
and e-wallets work just fine for that. Bitcoin´s true purpose is being
sound money with a supply that can´t be inflated. This would finally
allow people to store their earned wealth without having to worry
about confiscation or inflation.
