Kinda seems unfair that somebody's aunt should have to purchase insulin she needs to survive, like she shouldn't have to work harder to have the same lifestyle as someone without a disability. Maybe we should just give her the insulin she needs to survive, and compensate the people who make it out of some sort of common pool of resources everyone is required to contribute to, in order to distribute the costs more fairly.

That's basically what happened before money was invented. Imagine being a shoe maker and wanting to get some food, can you convince the sellers to take new shoes for the food/groceries EVERY DAY?

That's good work for a lot of reasons, but there's a world of difference between "open source and theoretically DIY" and it being anywhere near realistic for everyone to actually do it themselves.

It's good that I have access to advanced technology without having to have learned how to build it from the ground up. That's the whole point of civilization -- doing more together than we could do apart.
