It's a double-edged sword. I work for a company that has to deal with a fair number of online cheaters and fraud. It would be great if we could know who we were really dealing with for our financial transactions, or failing that, have a secure execution environment for our code so we'd have a solid place to stand on. Unfortunately the state of security on PCs is so miserable that they simply cannot be trusted. Game consoles actually do this kind of thing; the security architecture is rooted in hardware, partly to maintain the paywalls for entry to the console's market, and partly to ensure that the environment is secure against bad guys. Of course the moment you have system like this on a commodity PC you also enable a bunch of tracking, DRM and lockout stuff that is near trivially exploited by state-level actors and companies to whom you are just chattel to be sold or rented out. And that sucks really hard. I don't expect the masses to make good choices about security systems; they can be mislead, outright fooled, or simply drawn into poor decisions by trinket-class rewards. It's depressing.
