No. If you think about it, people who are actually playing records buy most of them, even if some people have records they don't play. Fifty percent of buyers only means fifty percent of records if all record buyers have one disc, which is clearly nonsense.
Similarly, we don't necessarily get a huge number of new users out of a 15% increase in records purchased in 2023, or whatever it is by year's end. We actually don't know a lot about the real market for LPs today except that the total number of new records purchased has increased in recent years. That could be because there are a lot of new turntable users, or some new turntable users, or replacement of older turntable users giving up through age, or just a million or so rich people buying four records each, or...
The numbers largely exist in a vacuum. The only pieces of information I can find are that a number of audiophiles lost belief in "magic SACD" from reading old forums, and a group of audiophiles old and new spending lots of money on new equipment during the 2007 recession/crisis/whatever your country calls it, that appear to be rich and redundant people, and some people deciding to become entrepreneurs or returning to the vinyl space in different ways also after 2007. The growth in sales, I suspect, includes a lot of suppressed demand from pre-2007 users.
There's actually little evidence for a "hipster fad" in the real world, as opposed to a few newspaper articles and how people were shown (still are, sometimes) in advertising material. As I pointed out, there's little hipster material in the recent chart information in posts here.
What I do know is that every time I've challenged someone buying a new system with a turntable with "why do you need the turntable?" there have always been records to be played. You can't take away the culture or the history from those who have it and want to do more.
Does it even matter? If people are believing the "massively better quality" lie and spending huge sums of money chasing that lie, or if they are compromising their digital listening unnecessarily when starting out to get high fidelity, then maybe that does. If record companies feed stereo digital users crap because "audiophiles buy vinyl, the rest don't need decent sound" then maybe that does. Otherwise...?
