Those kinds of rental, Netflix-like services are very clear on what they do. Pay a fee and get access to many games, you stop paying and they are gone. That's the deal and, investment-wise, is acceptable for many people. With Capcom doing that for a single game, it makes the deal unassailable: you own nothing, and yet you play only one game. And even then, I have the option of buying whatever game I could get for free in those online services, whereas with Capcom's offering, it's the only choice.
It's 20e for 6 months access, netflix would be over 60e for the same period, buying the game on the ps4 and keeping it for 6 months then trading it would likely cost you more.
It is a single game, if people want it there is an option if they don't they can skip it, but this is the effectively cheapest way to play resi 7 outside of PC piracy.
