Singapore has done this in a great way. As soon as you take your bags and go out there are display boards for SIM purchases - quite quick as well. Super friendly staff.
EDIT: changed Europe to Schengen.
For the casual traveler, it might not make the most sense, but for someone who does a lot of international travel, it's a great option.

Happily using my UK SIM and data plan while traveling through several EU countries.

The Brexit should fix that for you.
They delivered it to my hotel and it was easy to set things up.
As another example even though > 40% of users don't have a landline more often than not you can not call a Japanese toll free number (0120) from a cellphone.
There's also the issue that unlike the USA where you can't tell from the phone number if it's a cellphone or a landline, in Japan you can. Cellphone numbers start with 070, 080, or 090 where as landlines start with different prefixes. Because of this you're judged based on your number. A person or company without a landline is judged to be less trust worthy than one with. Oh, and landlines require $700 to start (though that may have been finally fixed)
The data is slow, but definitely good enough. It is good enough to use google hangouts to call phones back in the states.
The SIM is pay as you go, you can refill it at most newspaper stands.
It is only officially supported on Nexus and Pixel phones, which are great devices. You can get around the limitation by doing some Googling as well if you insist on using a different device.
"By no means perfect" doesn't mean "isn't perfect", it means "it's actually quite a long way away from being perfect".
I check in on the state of Fi every so often, and from what a lot of users are saying about it, it seems to be at best beta quality, and that's using the handful of officially supported devices. Perhaps in the countries you've been to with the device you use it's fine, but it doesn't seem anywhere near as reliable as picking up a local SIM.
Throw in the fact that it's not officially supported for most devices and that it's only available in the USA makes it a complete non-starter for me.
Also:
> if you insist on using a different device.
Having a device that Fi doesn't support isn't me being unreasonably stubborn like you seem to think. If Fi doesn't support the device that I use, that's Fi's shortcoming, not my own.
