we won't want to lower the bar in terms of the pilot's ability to stay safe. But we do want to lower the barrier to entry so that more people can learn to do it, do it safely, and enjoy all it's benefits.
I think 90% people who aren’t older than 60 or so would get the medical without a problem. If you would remove the medical requirement, you wouldn’t suddenly have double the private pilots. If planes were 1/10th of the price they currently are (both in purchase and operation), you would. Medical isn’t the main blocker to private aviation.
