Having some universal will controlling everything simplifies the world view a lot. If not, people need to explain why all objects, atoms and particles obey some (same?) physical laws. Even if we take this for granted, atoms still need to interact with each other all the time. For example, when planets rotating around the sun, do they (down to the tiniest particles) need to keep track of every other particle's position in order to calculate which direction to head next. Every particle must be conscious to sense, do the calculation and take action every moment. Each particle must already know the whole universal to calculate what to do next, without upsetting physical laws. Do they work in hierarchies, like all particles of the Earth group together as one and communicate with the sun as a unit? This might reduce some communication. Worst condition is: if there are n particles in the universe, and they are free, there will be n*n communications all the time. Are the communications themselves particles? If there is a universal will, it only needs n communications to control everything. It will even be simpler if all particles are just parts of the same universal dream.
