Here's my Mr. Brightside view of it, there is a Black Mirror-esque side as well as some humans build towards utopias and some build toward dystopias. I look at the quality of life and good side of things where I can.
I agree with most of what you are saying but that is based on the current era. Created scarcity and exclusives are annoying but there are pros and cons. Putting value to something will create markets and digital markets you can take your stuff with you.
When we get to more augmented spaces it will change the world dramatically. There will have to be some sort of digital ownership that is transferrable preferably a standard outside walled platforms. For instance artists or entertainment events that are unique are collectible.
Uniqueness creates value, value creation makes markets, this would create massive amounts of jobs and quality of life/livelihood if done right. Already it is spawning some amazing art and assets. It is in a pump/bubble but new things always come out hot, rework, then in the end the best parts do live on and the initial bubble might have even been undervalued, like the internet, or mobile. The augmented space will have all sorts of network effects like that.
It is in the very early stages, like a sketch of a storyboard early on in pre-production, everything early on in a way sucks, but we do know that over time the world will be more augmented and in that space digital ownership and uniqueness will be a thing.
The market is there now for collectibles and stores of value and it will only grow.
Take for instance you participate in a launch AR game for a launch event that takes place in your own environment with others locally or virtually, where you are in maybe a Stranger Things Upside Down world and you have to kill Demogorgons. The winner gets to keep the Demogorgon from that event. That item has value, you can buy a regular copy of one, but the original may be worth value over time. Do that same thing with any Star Wars, Marvel or other property, you start to see people will want those.
Or let's say you go to a concert and an event gets a recording from a musician that you get to keep and show others who are sharing your augmented space but you own it. You own the unique view or access, but others can get copies of other parts.
Or you watch a piece of digital art be created and the piece is sold and traded.
Like right now if I got to buy some sort of collectible from the first Half-life that was unique and part of it was my house or a yard can be turned into a level like datacore or stalkyard and I could have friends play it with a unique character added in from the Half-life launch it would be pretty awesome. There can be copies, but to have the one specified by the creator has some value and some uniqueness that creates that value.
Collectors love this type of stuff. Think of it like comicbooks, baseball cards, movie poster one sheets and unique characters. The fact that a collectible has value makes it more fun in a way but also creates value that can employ people and make a digital market. Markets like this will help keep people happy and doing things. The more people in the digital market the more jobs and resources out there. There is value in creating a marketplace that people can participate in that doesn't require physical assets/resources or even location. It could be used to help inequality and create economic markets. Economics can solve lots of problems but also require resources, if the resource problem is solved then it can be very beneficial.
These were just game/entertainment examples but you get the idea.
The coming eras of augmented reality and shared spaces on that will probably refine this idea more and more.
The far end of this is like some of the tech in Blade Runner 2049, unique landscapes, augmented bots that are friends/assistants that learn, companions like virtual pets, and other valuables that gain unique knowledge that cannot be replicated because it learned from your experience/event, but that is way in the future.
