> It's the large stream of perfectly usable e-waste modern practices emit.

From my point of view, the proposals suggested here, although difficult to discuss in detail because of how abstract they are, would not solve this issue in any meaningful way. By "meaningful" I mean that the cost-to-benefit or cost-to-regulation ratio would be rather poor.

IMO, the core issue with e-waste isn't necessarily bad practices by manufacturers, but rather consumer behavior. People often throw away 2–3-year-old phones that are still fully supported by the manufacturer. For example, with the exception of the phone I broke, I usually replace my phone every 5–6 years. Within that timeframe, I have the battery replaced by the manufacturer at least once, and the phone continues to work just fine.

This issue extends beyond electronics as well. People often throw away clothes once they "go out of fashion," which these days happens exceptionally quickly. The same applies to furniture, appliances, and other consumer goods that are often replaced simply because newer models are available, rather than because the old ones are no longer functional.

This is ultimately a broader issue of consumer culture and our tendency to replace things rather than repair or continue using them. I don't agree that this is primarily due to a lack of repair options or difficulty accessing repairs. In many cases, the means to repair these products already exist, but consumers simply choose to replace them instead.
