I mean, indeed, we are free to disagree when it comes to personal preferences. One of my keyboards is Das Keyboard with blank key caps too. But I would've used that to booster my claim, not yours - I can use that blank keyboard specifically because it's standard and same as my other keyboards:-). I spent hard earned cash on the t25 ThinkPad so I could enjoy a few more years of good keyboard before I have to switch to some modern laptop atrocity.

If you are switching truly different layouts daily, are fully efficient and have instant muscle memory with all, and never lose a moment consciously or subconsciously looking for a key, absolutely more power to you. I do not work like that. Having to hunt for Home key when I want to hit control-home drives me bonkers. Not having space between f4 and f5 is as silly as red turning lights - strictly worse for no actual benefit. Half height laptop up and down arrows are abomination upon IT Gods. And yes I've been a grouchy old man since I was a teenager :->
