>I assert that minimalism is directly at odds with self-sufficiency.
No, you've proven that it's not. Many people equate minimalism to just not having stuff. Minimalism means you have the minimum amount of stuff for the task at hand.
You have one set of ramps, one oil pan, one jug, one specialized filter wrench only for your car, and a ratchet that fits that filter. Exactly the tooling you need for the job, and nothing more. That is very minimalist.
A non minimalist person who changes their oil might have a half dozen old jugs half filled with oil in their garage, a drawer full of misc filter wrenches, and redundant ratchets.
