You can't completely eliminate the $2 tchotchkes. It can't and won't happen. First, because buying durable items is expensive in the short term even if it saves money in the long term (you can buy cheaper on the used market, but it has limited capacity: each item must have been purchased new by someone and then not used until it wore out). Not everyone can afford to lay out $100 to save $10 over the next five years, as an alternative to spending only $10 right now and buying a new whatzit in six months. Second, there are items you really do only need once, like favours for a kid's birthday party (actually, kid stuff in general, if you're only having one kid). Third, there are things that need to be strictly sterile when used (although those tend to cost more than $2), and disposable is several orders of magnitude easier to sterilize than reusable. We can push for products made of things like cast recycled paper pulp or biodegradable plastic where that's an option, but getting rid of all disposable products would seriously impact standards of living and expected lifespans worldwide.

You need a minimum population density for something like a tool library (or a Makerspace, which will typically have tools on hand) to work well. Say, 10 000 people within an hour's round trip? My hometown couldn't have mustered that. It's an effective solution in some places, but not everywhere. Likewise neighbourhood garage sales or swap meets or other places where people can swap tchotchkes they no longer need for other things they like better.

To put it another way: This isn't an ideal world. The majority of people had rather shoot themselves in the foot than consume less, even when they can afford to. Practical solutions need to take human selfishness into account.
