While I agree with the basic premise: every ADR has its pros and cons, I do need to comment on your statement about forces on the ADR. If you're living a normal life, you're putting 300 lbs of pressure on your ADR. The biomechanics of lifting ordinary loads, hopping up on a step, etc. generate a lot more force on your spine than you'd think. You may not hit 300 lbs every hour of every day but you'll hit it a lot more than you think you will. The person/being/committee/(whatever your belief system is) who did the original design of your spinal column was pretty smart in how it withstands loads without letting you realize how high those forces are.
