From my point of view the store model simply is more convenient for consumers and worth the extra price. I know that I stopped pirating games, music and movies when I started using Steam, Spotify and Netflix.
But is it a causal relation? You probably have a steadier income now than you had back then.
I can now actually afford games (in the quantity I consume them) now, so that question is fair. But thankfully the video landscape fractured, now you better have NowTv, Netflix, Prime and Disney+ and you still can't watch all. I've started pirating again after 10 years or so of complete abstinence. So I think it's causal (if you have money)
I have to say that Spotify completely changed the way I listen to music, and I would really struggle to go back to buying individual albums.
I think of the three, movies are the only one where the "more disposable income" part of things is the dominant component of why I changed behaviours.
“Russia now outside of Germany is our largest continental European market [...] The people who are telling you that Russians pirate everything are the people who wait six months to localize their product into Russia. It doesn't take much in terms of providing a better service to make pirates a non-issue.” [0]
"We think there is a fundamental misconception about piracy. Piracy is almost always a service problem and not a pricing problem," he said. "If a pirate offers a product anywhere in the world, 24 x 7, purchasable from the convenience of your personal computer, and the legal provider says the product is region-locked, will come to your country 3 months after the US release, and can only be purchased at a brick and mortar store, then the pirate's service is more valuable." [1]
I for one absolutely have more money than I once did, but to be honest I stopped pirating long before that in '09 or '10, once I realized that the then-ridiculous Humble Bundles and Steam sales reduced the actual expenditure required from "gotta save up" to a mere "gotta skip buying takeout tonight". Of course the sales have decreased in quality since then, but so too has the number of games I want to play, and the time I can spend doing it.

I don’t pirate games and music because Steam and Spotify (or Apple/Amazon music) are a better experience than piracy.
