They can, for sure. I am someone who values a good mechanical keyboard, but I just need one and it will last me decades.
Investing once into something that feels good to use every day is worth it totally.
As a musician (and electrical engineer aka someone who trusts measurements and blind tests over golden ears) I like mechanical keyboards because there is "more expression" to the typing. With black linear switches that can be typed totally silent (e.g. if I record, mix or my girlfriend is asleep) or hammered on if I feel like it.
It is sturdy, doesn't float around on my desk, the keycaps feel good etc.
