This would create a game that is just complete mayhem.
I don't want Minecraft in space.
I want the Elite universe and feel in this game. Seeing pink unicorn racetracks on random planets, and giant phallic space stations or even worse buildings that are placed or shaped to form some kind of racist, bigot, political or otherwise offensive message, e.g. buildings laid out to shape a swastika, or space stations in the shape of salutes... no, just plain no.
I have zero need to see these things in Elite.
If I want that nonsense and so-called creativity in games I will simply go play Minecraft, Space Engineers, Medieval Engineers or any number of other voxel based building games on the market.
As far as building goes the only thing I really want or need to see in this game is deployable equipment, such as surface miners (placeable on planets, moons or asteroids).
