Why are you lecturing me on visual impairment and disabilities? At no point did I claim you ignore that user base.
Many of us may not particularly like touch screens, but an incredible number of computers that run Linux/BSD these days have touch screens. Things should work out of the box for these computers whether or not you want one.
Okay so after all that we get to the root of the issue. Instead of a good traditional desktop experience, you want to provide a mediocre desktop/touch hybrid experience. Instead of doing one thing well, the aim is to do multiple things poorly.
