The simplicity of the concept doesn't have much bearing on the reality 
of trying to make it.

Metallised film capacitors are made by evaporating metal to create metal 
vapour which you let condense onto the surface of a plastic film - the 
metal layer is about one atom thick. Thinner and it won't conduct 
electricty. Thicker and you are wasting metal. You wind two layers of 
metalised film together to make your actual capacitor.

There not a lot of room for creating more precise clearances.

Plasma has a nasty habit of chewing up anything that it touches.

Usually because the people touting them skip over the realities of 
making them work and keeping them working.
