But can it run proprietary software used in the industry? From Excel to Photoshop, if you are in a collaborative professional environment, you can't run away from those, and don't tell me you can use the alternatives in Linux, because no, you can't. This is not linux fault, but it's still an issue you can't handwave.
I love linux, but you can't expect people to adopt it just because it's objectively better than windows.
I wish Wine worked well enough to use Excel. We are not talking about adding up numbers in a cell. Once you include macros, or a reference manager in Word, Wine is not good enough. The same can be said about propietary software, like autocad, or software used to control equipment. Also, good luck convincing a regular user to get familiar with wine.
WPS is great for simple files. Again, not good enough for complex files, especially if it is a corporate collaboration environment. I have lost count on the amount of ppt files that didn't display well when it used WPS.
Every other year I try all the alternatives you mention, hoping they got better, and I always come back to use a dual boot or a virtual machine, which is not a thing your regular user wants to do.
