Except when no one provides such products, or the only ones fitting that goal require very large sacrifices elsewhere.
Look at mobile phones and tablets before the EU rules. Finding one that charged off a standard USB socket was near impossible.
Again with mobile phones, since there is no right to actually own and control your device, finding a phone that allows you to root it constrains your choices in just about every other way, including ways that have nothing to do with being able to root the phone, such as being a second class citizen from your carriers point of view (e.g. Verizon refused to enable international calling for my phone because it wasn't an "approved", aka Verizon branded, phone.)
So, right to repair regulations mean that I wouldn't have to decide between being environmentally conscious (if that open is even available) and having a product that works.
> wages are the real issue, not cost of spare parts.
I can and do perform many repairs myself when the device allows a repair to be done (even sometimes when it doesn't).
