Don't get me wrong. As I said, I'm a font nerd. My old blog has fonts I paid actual money for, which was otherwise exchangeable for goods and services in the real world.
I like fonts. I get why people like fonts. I just don't think they matter.
Now, if Computer Modern was an important professional signal, and it was the case that Monotype owned its copyright and rapaciously charged for its use, that would matter quite a bit. But that's not the case; ironically, the one font we can think of that has professional implications is under an open license.
There is a battery of commonly-used fonts (the Microsoft fonts, we might as well call them) that are professionally important. But they're also universally available; they argue against the idea that font licensing is all that meaningful, as well.
