Precisely. So if my logic "sucks" then why do you offer only a quote that does not address this point directly?

To separate energy from matter in the manner you suggest is certainly material for a nice and purely intellectual exercise, but we do experience this world physically, and energy comes from several materials. Petrol, for example, is something we use to release energy, but it is also matter. I do not believe we have found a process by which we can extract or use energy from a source that was not material, as such physical, as of yet.

I know some pretend to feed off plasma, breatharians as I like to call them, but seems like they all cheat.

The physical experience this world is to us may be an illusion but, you know, I doubt that.
