You've got that right! I have a beautiful LSI 11/93 CPU board here
given to me as defective. Scoped the problem to bad output from a GAL!
I don't think I will be able to find one of those anywhere unless i can
find somebody with a board that has some other fatal flaw!
cheers,

As you say, to each his/her own.
But although mechanical devices are indeed more prone to issues, the same
argument could be applied to the rest of the system; when your unobtainium
PAL or LSI chip fails you'll probably replace it with a modern replacement.
Just a question of where you choose to draw the line.
Personally, I just spent some time this weekend reviving some obscure IMI
hard drives that hadn't been run for at least 25 years and it was a real
delight to not only get them going again but to discover that one had a
functional OS installation on it that I thought I'd lost long ago.
I suppose there's some of that the very first time you get your Gesswein
emulator working, but it ain't the same thing.
Another issue is that I have several hundred floppy disks, some with fairly
rare stuff on them; maybe I'll get around to archiving them some day but in
the meantime they're fairly safe on disk (unlike the box full of extremely
rare Burroughs paper tapes that I threw out before I discovered that there
are folks who are actually interested in that kind of old crap ;-)

Agreed; might as well just replace the whole system with an emulator

Why would one want to do that?
My goal would be the opposite. Upgrade all vintage computers with floppy
drives ;-) My experience is that, if handled correctly, floppies are one
of the most durable media, and they are definitely more fun on vintage
equipment than any form of modern replacement. For exchanging data
between
the new and the old world, maybe it can be an option. But for classic
computing? No way I would replace a floppy drive if it isn't broken.

To each his own. My interest is not in museum pieces that stand on a shelf
and look pretty. I like to actually work with them. Mechanical disk
drives
are so old today they are prone to constant failure. None of my
original TRS-80
drives still function. If I replace them with TEAC FD55's they are no
longer
original so what difference is there if I replace them with a GOTEK and
USB Stick?
And the disks themselves become unreliable with repeated use. The
replacements
also allow for trying things the mechanical disks are incapable of.
Like really large
floppies with255 tracks.
