Questions for physicists

If you think the universe is quantized, then why not quantize everything from the start?
If you think the world is relative, then why are our always computing relative to gravity?
If you think the there exists a Unified Field Theory, then why are there only three unified fields?
Why would you always assume the EM fields are at right angles?
What happened to impedance between E and G?
Why isn't charge a general characteristic of all fields?

I have a few more.
