No, it doesn't follow. I demand that my country enforce the freedoms guaranteed in the US Constitution; in particular the rights of freedom of speech, freedom from unreasonable searches, equal treatment of people regardless of race, etc. Reality is that in many areas, local policemen deny people those rights on a daily basis. By your logic, what would be needed is a layer in between citizens and their local policemen to make it look like those rights were in fact being preserved even though they weren't. In fact, the correct place to fix the problem isn't there - nor is it necessarily helpful to directly attack the local police. The problem has to be fixed at the higher layers that are responsible for condoning or even promoting such abuse. (It might not be the best analogy, but it's the one that came immediately to mind. The point is that it's erroneous to assume that the place where problems are experienced is the place where they need to be fixed.) -- You are arbitrarily calling network conditions "reality" without recognizing application needs as "reality". This may be why you persist in thinking that the problem can be fixed by creating an "illusion". What we need is not illusion, but to rearrange functionality so that there is a good match between what the network provides and what applications need.
