Decorative and entertainment applications still need paper, digital completely breaks immersion in things like LARPing, and there's all kinds of crafts that need them.

Plus, we still need them for labeling and making high detail front panels at home.

Other than that, I'm all for completely going all paperless, it's often months in between the times I actually use a pen, and I'm usually rather annoyed if anyone tries to send physical paperwork in 2022.

Unfortunately every reason I'd print something requires color, so inkjet is pretty much the only option.
