Umm... Who would pay $149 to use a font? Maybe I'm not enough of a typography nerd, but I find the free choices (JetBrains Mono, Iosevka, Fira Code, ...) quite enough.
I don't know if you've looked at the cost of other fonts, but $149 is very much on the "cheaper" end. And it's worth it to me to have a font I like looking at, as I'll be looking at it all day every day. Better yet if you're someone who enjoys the ones you listed. It just so happens that out of the list of 4, MonoLisa appeals to me the most.
