Maybe "this font is offensively priced to the point where I immediately think the person selling it is a criminal using this for money laundering, or clinically insane" and "it's hard to sell enough fonts to live off of" are related?

Maybe if charlatans didn't say with a straight face that a font should be sold on a subscription model they'd sell more? Maybe if it didn't cost as much as a car they'd sell more?

The people who make and sell fonts are probably the best people to be setting the price, and have tried lots of options.
