I guess we to agree to disagree.
What I meant to say when I reacted to your first post, was : don't take for granted that if creating actual objects from 3D, even combined with electronics, is more gratifying for you, it would be for everybody, because it's simply not the case.
What's fantastic for you may not be as thrilling for other people, such as me. I don't care of having any of my models stuffed with leds and electronics, even to become radio-controlled, because that would not allow me to create Sci-fi or fantasy animation, which is what I thrive for.
You say "anythnig is possible with 3D-printing combined with electronics", and I say it wouldn't give any benefit for what I want with my models.
Because I want my models to be part of animations with a lot of explosions and lens flares and VFX, and I create them for that very specific purpose and that is way more gratifying for me than having them transformed as another model kit, because I just want to tell stories.
As I said in my initial reply : it really depends on what you're after.
As a concluding thought, here is my personal walk through 3D and animation. It may explain better why I don't care about creating actual things :
