In future this won't be possible - it relies on someone being able to get the full game code. But we're at a point where consoles are going to download bits of a game at a time... ...and there will be components that only function when connected with a live server, generated by code no-one but the publishers have access to. E.g. NPCs will be backed by LLMs hosted in some datacenter somewhere...
In any case, the days where games are "done and released" are probably over. To increase longevity, games will have elements added and removed over a period of a couple of years. So no, you will. not be able to pirate them, and even if somehow you get the full code, it'll be "one version" of a game that can be completely different month-by-month.
In practice, I think we're heading into "pay by hour" gaming.
