I think a good way to ensure repairability is to require manufacturers to honor a relatively long warranty. For example many large appliances have 1 year warranties. After that you have to pay to repair (which is often 25-50% of the cost of new and not guaranteed) or toss it and buy new. If there were required warranty service based on waste generated from an item, eg a refrigerator must be warranted for 20 years, then you would see much better reliability and repairability. Smaller, cheaper, more tech heavy items might have shorter required warranties, but the point is that you need to align the incentives by forcing manufacturer to bear the cost of the repair.
