The old Strads etc are loaned out to musicians to get played generally by their wealthy owners.
These are going to be put behind glass.
But if it makes somebody happy to do it, more power to them. If they can drop that kind of coin, they're realistically already paying out the nose in taxes and other things, and for them, it's not a big deal.
Sort of like buying a 100k sportscar or whatever, it's just what makes you happy and you can.
I'd play it if I wanted it, and if I could afford it, I'd get it. Same as anything else.
Chances are it wouldn't make me any happier than any other LP I've ever played but I don't hate those who can swing the $$$.
It really wasn't an "ordinary" instrument back when it was made either though, those were stupid expensive pieces of wood that you didn't casually buy even then.
Not a house-worth, but a large sum. Same with any of the old instruments.
Thing to remember is that even clunkers appreciate with inflation in ways that are boggling.
I can see paying six figures for that before I could see paying $500 for a Teisco.
