I prefer indestructible and long lasting devices-as-tools. I want more appliances, fewer janky assemblies of parts more likely to fall apart or fail me when I need them most.
Put another way, the goal is not "easier to repair", the goal is net fewer devices requiring repair, net fewer repairs.
One of those is actually better for the environment than the other, and it's not the one that churns through parts for people who want to repair or tosses more devices in the trash for people who prefer to just buy a new one.
The thing that's good for the planet is devices that last. That's the goal.
TL;DR:
If you want to legislate something, legislate lifetime warranties.
