"I bet everyone would love to have a turntable and vinyl collection of the favorite albums..."That is a bit of a stretch. People do not even have favorite albums these days, much less are they interested in collecting them on vinyl in any number significant for anything except theoretical debate about marketing power. I know exactly zero people interested in having a collection of favorite albums on vinyl. I know one youngish lady (late 20s) who was very excited to buy a record player. She put it in her wish list on Amazon. A little $80 machine. She has no records and is not really planning to start buying them. She wants a record player because it looks cool and she wants to be cool. That is in her words, not mine.
What the heck, even I am not interested in having a collection of my favorite albums on vinyl. And I actually have it and have just (this morning) bought yet another copy of Exile On Main St. (half-speed master) on vinyl which is far from my favorite album anyway.
Those youngster LPs will find the way to thrift shops, once the urge to be cool gives way to reality of life and fitting the crib in the room becomes way more important than impressing some new companion.
