I think what was expressed was that there are exceptions (so, not literally always). Like road trips. We don’t need to get hung up on this. There are phrases that apply like “for all practical purposes.”
And having an L2 charger beyond a simple 220 wall outlet is no faster than the 220 wall outlet. Sure you can upgrade and get a fast L2 charger but you can more cheaply upgrade your 110 wall outlet to 220 and it will be just as fast as any installed L2 charging unit. In other words the installation of a charger is superfluous when it comes to speed of charging, which is what you have been talking about.
You might have heard of people getting faster charge times with an L2 charger versus their friend’s 220 volt outlet. But the opposite happens too: 220 outlets vary depending on amps, and so do L2 chargers. It’s possible to have an L2 charger that is slower than a 220 outlet, depending on the amps of the L2 charger and the amps of the 220 outlet.
