I have no business with resale tbh, the only time id use it is when that particular game isnt getting made copies anymore and the digital storefront is dead, but in that case i would probably be able to emulate it on pc since the console would be old AF by the time that happens.
Also what's with me having a 'lack of self awareness'? Wasn't everything i stated right?? if a game goes down there will most likely be a site that helps with archiving the digital formats of those games- i mean look at wiiware and its closure in early 2019- there are sites up today with the wad files of these games readily available for download.
Your personal use of resale options is besides the point really. The lack of option to resell, and thus effective lack of ownership, is however one enjoyed by everything else in life and physical games, the only reason you don't in downloadable games is because lawyers or arsehole business types.
So downloadable games are generally (online only DRM might not be cracked in time, there are a few unplayable games already out there) made available by third parties, just like ROMs of physical games have been for... longer than the internet really.
Both represent a failure of the market and the market, or a segment thereof, working around it but it is still a failure. Downloadable games is not a solution to it though, and with the lack of resale also means that when things don't go in some hypothetical future (I do like to remind people at this point plenty of big companies have shuttered DRM encumbered services and also plenty of others have gone bankrupt) but 3 years later when some music owner, owner of car/gun/texture, general IP holder or whatever says nah not renewing.
That would be the lack of awareness.
