Gamers spend millions on registering assets in marketplaces: game skins, mods, extensions, assets, it is all just buying records of ownership, but in a centralized company-owned database rather than distributed ledger.

That’s not the point.

People do not want to think of the things they buy as sellable assets. It’s just a shirt. Just let me buy it. I give zero fucks about your choice of backend data storage.

I see—you are saying gamers don’t really care about whether an asset is sellable; but the same is true of most things we purchase. When we buy a book or a vinyl record, we don’t think about its market value, until the day we stop needing/wanting it and realize selling could provide us some return. In those moments, it’s nice that there is no company that can block you from selling on the open market. Many gamers would appreciate this (and do, when they are given the ability to refund digital purchases they no longer want/use).

No, you don’t see. People don’t want their stuff to be sellable.
