I see your point, and I know musicians who came up under the old system, but the distribution networks have changed, vastly.
Case study: I read about an album (Jónsi’s Go) and followed a link to check it out. The entire album was available to stream, for free, as often as I liked, without having to go through iTunes or whatever as an intermediary.
I could buy the DRM-free files right from the web site. If I wanted merch or CD or vinyl, there were links for that. (I wound up getting a CD via Amazon 'cos I was still using my car CD player at the time.)
Now, this is a bigger artist, so he did do an international tour. The friend I went to the show with bought me the DVD to accompany the album to pay me back for her ticket.
The DVD is region-free, says so right on the jacket. So the merch people only have to worry about one inventory no matter where the tour goes. I don’t know if it’s DRM-free, because I’ve never bothered trying to rip it.
Point being, this is a very different approach to marketing and selling than a traditional label, even one well-versed with on-line marketing.
An inconvenient truth about the music industry that’s been a thing since the days of cassette is that the people who make illegal copies are also the biggest buyers and promoters of music. A few artists have accepted that and successfully made it part of their marketing and promotion. Many more have done it unsuccessfully for various reasons.
And then there’s the ones who don’t get it (hi Metallica) and persecute fans.
Compare Garth Brooks going after used record shops with The Grateful Dead having a space just for concert recorders.
