If Sony wants to entice people to buy a PlayStation in the next generation, they compete price-wise with Microsoft. If Microsoft offers games for $10-20 less and discounts them faster, the incentive to own a PlayStation diminishes. So no, so long as the platform refreshes and consoles offer multiplatform games, there is no monopoly.
And rather convenient to ignore Steam. I'm pretty sure everyone owns a computer that has Steam on it. Consoles then have to compete with PC for price as well, which they already do. I assert that PS Plus and Games with Gold wouldn't exist as they are if Steam were not a thing. They certainly weren't done out of the goodness of Sony or Microsoft's hearts.
Not that either of us can prove our point, since we still live in a world where retailers are dictating the online distribution pricing for games.
I never argued to the contrary of any of the things you state, far from it, in fact. Please feel free to point out where I did, I'd like to rectify that mistake if I in fact made it.
Seems to me like you're looking at what I proposed as a condemnation of people justifying their choice to buy physical media when I never presented that argument.
Sorry mate but no. These are digital ecosystems, like if you buy an iPhone and use iTunes then all your purchases are tied to your iTunes account. If you want to buy a tablet, do you go for a cheaper Android with better specs but start from scratch or spend more to get an iPad but you can migrate your stuff? If you only have a few items then it's not a big deal, if you're spending hundreds of dollars on apps, videos and music then suddenly that cheaper Android isn't cheaper any more.
Microsoft can offer a cheaper console and cheaper titles but if you've already spent an entire library's worth on your PS4, what do you do? What if the PS5 is shite? Write off your purchases as a sunk cost or persevere?
PS Plus has nothing to do with Steam and everything to do with Sony trying to justify charging for their service. PC gaming in general doesn't impact consoles, the vast majority of people can't be arsed with PC gaming no matter how cheap or flexible it is.
The vast majority of people who have a PS4 or Xbox One probably never used Steam in their lives.
Unless digital stores are completely open for anyone to sell keys, then no they are monopolies by the platform holders and unlike older generations, you can't sell your collection if it's all digital.
The argument that you're left without online servers or patches doesn't wash because the digital only future leaves you completely cut out, whereas at least you have v1.0 on your retro console on disk.
My biggest problem with people who go all in for digital is that they support terrible consumer practices and ruin it for the rest of us.
