The only issue I see is that when it breaks

That's a pretty big issue, and that's likely a huge contributor to issues like ewaste. If someone owns a computer and the memory goes bad, they buy a new computer instead of new RAM. Likewise with batteries on phones, capacitors on appliance circuit boards, etc. There's so much that used to be regularly repairable that could still be repairable if people understood the basics of the tech they use. But when it stops working, the knee-jerk reaction is to replace it, not repair it, esp. when it's generally cheaper to replace than have a service tech come out (when 50 years ago, many would just repair it themselves using the provided service manual).

I like to blame manufacturers here, but a large part of me has to acknowledge that a lot of people wouldn't bother even if they had all the documentation readily available. A little bit of knowledge about how things actually work can go a long way in reducing waste throughout society.
