In addition, the benefit is a bit ridiculous, like that of DRM itself. Even if it worked, literally your "trusted software" is going to be running in an office full of the most advanced crackers money can buy, and with all the incentive to exploit your schema but not publish the fact that they did. The attack surface of the entire thing is so large it boggles the mind that there are people who believe on the "secure computing cloud" scenario.
