Had we kept the 28 year copyright duration from 1831 almost all ROM images would be in the Public Domain now.
For example indie creator studio makes video game for the PS1. It's a huge hit, they go on to make other popular games, and one day Microsoft buys them, morphs them into an in-house team. And then one day you realise you're arguing that, Microsoft (now the owner of the license) should release this Sony Playstation game. No. Not going to happen.
When this stuff happens for individual humans, often even if the money doesn't mean anything to one person who is an obstacle, it does mean something to their co-creators and they'll do it for that. For example it would be possible for Alan Moore to have blocked a lot of stuff that uses his work, from the V for Vendetta movie (which lots of people liked but I felt missed the whole point) to the re-issues of Miracleman, but while Alan doesn't care about money, the artists on that work do, and him blocking it would hurt them. So e.g. that's why modern copies of Moore's seminal run on Miracleman say they're by "The Original Author" in big text but never mention Moore by name, that's his condition, he doesn't want the Mouse's money, but his artists do.
Corporations don't care though. If they can inconvenience a modern competitor by snuffing out an important cultural artefact that is exactly what they'll do.
I'd actually advocate outright abolition of copyright. The associated moral rights have some place, but copyright is almost entirely a means for corporations to try to control culture for their own profit and we don't need it. But 28 years is a more acceptable middle ground I guess.
That still protects the individual artists and perhaps the Banskys but doesn’t unnecessarily lock up these old games
Much like Netflix, the reality is that people aren't actually very interested in old shows apart from a handful of super famous perennials which are already available anyway.
They say they are in surveys, but consumer behaviour does not back that up. They just use newer content in practice.

I didn't know how to filter out the romhacks, if you scroll down the majority of the collection is original games.
The demand is there, it's just a question of having a convenient enough package
They already do this, you need a Switch online subscription to access the NES/SNES ROMs they have available
There's not a lot of incentive for some of those groups to come together, but I imagine even if most could be assembled, Nintendo would be particularly resistant.
Technically, GameTap had some really neat little features. For example, it would track your high score for most emulated games, and for really old games where the score would rollover to zero, it noticed that and would let you see your effective grand total score. So there would be a global Galaga leaderboard that could happily go into the millions.
Regarding the success of the service, Gametap was live for a few years. It totally had its shot. GameTap was regularly advertised on TV. It had a pretty big library covering a dozen or so platforms: Several Ataris, ColecoVision, Intellivision, Sega, PC games, and more. They did a few high profile things like buying some failed MMOs and keeping the servers running for all GameTap subscribers.
At the end, I think it turned out that the folks who get really excited about playing ColecoVision games are the same folks who are very comfortable downloading ROMs.
I think it may just have been ahead of it's time in terms of model in the era of battlepasses, paid online and gamepass, as well as monthly paid streaming services in general.
Here's a fun technical secret about GameTap. Several of the companies that we bought licenses from barely knew they owned the games and definitely didn't have any original binaries or source, and for the obscure consoles/titles, we sometimes could only find cracked versions online. Those would usually have crack intros (it was the birth of the demoscene!), though, and we clearly didn't want to use them. Ultimately we cheated. We just launched the game by loading a save state just past the crack intro.
