Yes, because as you said these applications only run on Windows. How else would you get around it, if not by running some form of Windows? At least this way, the core system (and 90% of general purpose applications) could remain on Linux.

You can just use the install unlicensed, or, if your computer came with a Windows license (as most do), you can extract it from the motherboard and use it to activate the VM. Not sure if that's allowed in Microsoft's ToS though.
In any case, I'm not going to try to set up a Windows VM on my Linux computer, I don't have the room or if I had it would be better used for other things. And I just abhor using Windows, whenever I have to use the wife's PC it's hell. For her, too.. she can't find anything after she's saved something, for example. And I don't have a Windows license, never had, my computers are all bare when new. In any case, it defies the whole purpose of not having to run Windows. Now, with Windows 11, it seems to be even worse. And I have zero idea on how to install Windows from scratch anyway - in my case I would probably even have to install a Japanese version, as is installed on my wife's PC. Well, not going to happen.
