The charging network argument is getting less important in densely populated Europe, and at least here in the Netherlands. For fast charging I usually charge at Shell Recharge because it's cheap with my card (for my boss, but small company so I try). Otherwise there's always a Fastned, Ionity or other party. And there are so many destination chargers that I don't really hesitate to drive anywhere. And anyway you can charge at Tesla too if there is availability I think, though for the reasons stated above I haven't needed to.

And now other brands are coming out with loads of relatively affordable 100-150kwh+ options. At that point a cross continent vacation is still a bit of a hassle, but for daily use that's more than enough since you mostly charge at home or at a destination anyway.
