Well if there’s lots of copies floating around and no demand then yes, should be cheap. But there’s a caliber of record that will never sell at a steep discount at an op shop. Records in high demand that for a million copies in existence, a million people want to own them and they hold their value. There’s also pressings that come into it; a pressing from the 1980s will always be more valuable than a modern pressing because of scarcity and older vinyls have that nostalgia factor.

I agree with you though that records are very overvalued.
