Here we go. Vinyl is irretrievably flawed, vinyl lovers are in denial, etc, etc.
The truth is that the best of any format sounds great. It's also true that it is more expensive to get a decent sound from vinyl, but once you get to that point, it does sound a bit special. At its best (which is undeniably expensive), it can rival, perhaps even better other methods of music reproduction. You don't have to spend telephone numbers - £2k tonearms, etc - but the base/entry point for quality is higher than it is for other formats.
If you have a strictly utilitarian approach to life, vinyl probably isn't for you, but the majority of us don't live that way.
Yes, pride of ownership is a factor, but a liking for nice things applies to many aspects of life. We don't all drive economy cars, wear simple, functional clothing or eat bland but perfectly nutritionally balanced food. We like a bit of luxury and even a few toys. Nowt wrong with that.
In my experience, those who claim vinyl is fundamentally flawed (what method of music reproduction isn't flawed in some way?) have never heard it at its best.
