When one guy (this guy certainly isn't the first or the best) makes a thing that manages to catch fire a bit, the big players can simply buy it. They can even force a sale, or otherwise refuse to let it be widely distributed or marketed. That's the stick, the carrot is that if it's genuinely resonant with people, they can just throw you life-changing money (i.e. pocket change for them) and generate billions for themselves.
Music barely democratized when production got in reach of the masses; as film production got cheaper, quality indy films became fewer and harder to find, and never in a theater; and as video games become cheaper to produce, Steam can make or break any of them at will, and do the same as any other monopolistic distributor - if they don't, it is by choice. If it is by choice, the person who made that choice will eventually be replaced with somebody who mocks that choice, because they will pay the most.
"Efficiency" doesn't benefit individuals at all without antitrust; it is extracted like any other value. One thing that changed about the music industry is that when it was a thousand companies, you could just bring talent and they would put you where you would earn them money - now that all media is owned by a few companies you are literally expected to bring a hit album to a record company before you get signed, and getting signed then gets you access to the media, wide distribution, and venues. They don't really even pay you, you pay them. Since they control distribution, they don't even really need talent - they can just imitate it. The reason they're giving you a deal is in order to tax your success.
The impact of the Industrial Revolution was that people were forced off of their farms, which were merged into super farms, exactly as they expected. They went from working for themselves for six hours a day, and living in relative comfort, to working for 14 hours a day and living in crime and disease ridden tenements. Their lifespans decreased by a decade. The air, land and food was poisoned. They likely died before they saw any improvements in this, and those improvements eventually came from anarchist and communist unions, and their own education about how they were being used. Then those unions and organizations were crushed, and their names were cursed; even somehow the word referring to the members of the "People's Party" became an epithet to throw at people who thought government had a responsibility to the people. Term limits were introduced so they wouldn't have a president like FDR again, although FDR's reforms ironically served to weaken the unions that saved them, so they could be destroyed completely subsequently in the name of war.
Even today, people say "you can't yell fire in a crowded theater" and don't know that it is something a judge said about a left-winger passing out antiwar pamphlets. They just repeat it, because they heard it. That's what happens when someone controls distribution.
I believe in efficiency. Efficiency under capitalism without effective devices to maintain competitive markets is simply more value for the parasites to extract.
Everybody found it easy to imagine the impact of the Industrial Revolution. That's why they broke frames.
