If I lived in the 1970's, and I had a U-Matic tape machine, I'd tape all the episodes of New York era of Pyramid from $10K to $50K.
This is
truly not meant as a criticism of you or your comment, but no you wouldn't. For the same reason that people in the late seventies didn't record every single episode of their favorite game shows when VCRs were actually something people had in their home. Even beyond the practicality and expense issue, it's just something that would never have occurred to you to do. Or anyone else. Maybe you tape an episode here or there, like Andy Warhol did, or like I did in the 80s when I got my first Betamax. (You're welcome:

Now if you had a time machine and wanted to go BACK to the 70s and record those shows on U-Matic, I'll come along and help!
OK, I didn't mean for the window to open up, and I don't know how to fix that.
