The current limits of Bitcoin *enforce* that "Virtually nobody" uses it — like, uses it at all. It can't scale up to even just the monthly rent and bill payments in just the city limits of Berlin, let alone e.g. people in this city just buying lunch and nothing else anywhere else in the world. The talk about e.g. it being layer-0 and day-to-day stuff being level-1 or whatever, that immediately deletes all the supposed benefits that bitcoin advocates for as it becomes "here is a bank that is backed with BTC just like normal modern ones are backed with fiat and old ones with gold".
