Anyone else with comments, please feel free to weigh in, but please, PLEASE, do not address the wisdom or folly of counting time spent enjoying a hobby. Please start another thread for that discussion.
You're trying too hard. There is also an intangible value to being able to load ammo and/or shoot when all the stores and all the web sites have been sold-out for over a year. Whatever that value, IMHO it overwhelms a lot of your detailed cost analysis.
