This claim that system fonts are the "bottom of the barrel" is just so clearly false that I don't understand how you can be an advocate of typography and say it. Both Microsoft and Apple put huge amounts of effort into typography, contract or employ well-regarded designers, and their outputs are themselves well-regarded.

If you wanted to say "most of what's on Google Fonts is bottom of the barrel", you'd have a colorable argument. But that isn't what you said.

San Francisco is a great font. Arial is a perfectly functional semi-clone of Helvetica, Times New Roman is a decent interpretation of Plantin. Roboto is an interesting mash-up of Helvetica, DIN, and a few others.

System font from a web standpoint means you get one of these depending on the user's choice of phone, desktop, and/or browser.

It is somewhat like buying art because the frame covers a blemish on the wall. That the print inside the frame might be of a famous impressionist painting does not mean that the frame or the print necessarily go with the room.

The car analogy involves a car rental place - that they may give you any one of several newish, functional and even stylish vehicles does not change that you may often wind up being paired with a vehicle mismatched for your function.

Around the time Matthew Carter was creating Georgia, one of the most widely-used system fonts in the world, for Microsoft, he was also widely considered one of the best typographers in the world. Georgia is not hotel room wall art.
