The thing is with Alice you can easily get hot-swappable board with different switches and keycap profiles and it costs less than $200.
While I have been eyeing these "cup" style keyboards for years, I feel very hesitant dropping $400 on a keyboard when my Alice is "fine".
Maybe you are right that Alice is a half measure and going full hog is the way, but I could also be spending $400 on a keyboard and another $100 on shipping on import tax just to end up with a keyboard I don't use.
