encryption decentralizes everything - if you can run your code on any machine with cryptographic proofs that the code you're executing is the code you want and that the runtime is not accessible to the host combined with the encryption of data (which is relatively solved problem already) then we can push the cloud is somebody elses computer meme to the max.
decentralization of compute is a game changer, it is also something that can potentially bootstrap a lot of decentralized economy. Every spare cpu/gpu cycle and internet connection can and should be monetized.
My company is doing what you're describing.
I believe we'll make you very happy
