You have it backwards. The mono mixes don't destroy anything, they are the definitive versions of the songs. It's the stereo that's destructive.
You can nitpick the mono (or the mono versions of a couple of songs), but the stereo "mixes" on almost everything are dismal. Put on some headphones and listen to Rubber Soul. If you can. It's painful. The ridiculous, unnatural hard panning (music all the way left, vocals all the way right - or vice versa, you know, to change things up) sucks every bit of the power from the songs. By the time of Revolver the studio technicians who did the stereo mixes had learned to leave some things in "the middle" of the mix, but the hard panning of other tracks is still there.
Your examples are from later records, the two albums that kind of sit right on that cusp when mono was going away and people were learning how to do stereo properly. But when you say, "Mono lovers can go screw," you're making a blanket statement about the mono versions that just doesn't stand up. I understand that the stereo versions are interesting to listen to, as a musician, because you can hear things you might not hear on the mono versions. But as a musical experience the exaggerated "stereo" - of the first seven albums, at least - is awful.
I get it, for most people those stereo versions are what they know. Over the past few years when I've talked to anyone who was interested about the mono versions, what I usually hear is that people prefer the stereo. When I ask why they say it's because that's what they're used to. But as a kid in the 60s I didn't hear any Beatles music in stereo. I heard it on AM radio and my little one speaker record player. When I heard the stereo versions later in life I was shocked, and they actually turned me off The Beatles music for a long time. If the stereo was all we had, I really couldn't listen to their pre-1967 music.
The Beatles recorded at an interesting time, straddling the mono and stereo eras. But with the exception of the later albums that were mixed in stereo with the input of the band, the stereo was absolutely an afterthought (and an unapologetic commercial ploy to sell more records by clumsily catering to a new technology), and it sounds like it.
I really want to draw an analogy between the after-the-fact stereo mixes of the mono albums and the posthumous Black Sparrow books, but I won't.
Oops, I guess I just did. ;)
