I disagree, if you buy a washing machine and it breaks every 5 years forcing you buy a new one then you are spending maybe $1000 every 5 years.
But if you can repair this washing machine you should easily be able to keep it running for 15-20 years and only spend at most $1000 on parts. (My current washing machine is over 20 years old and I can still buy parts for it. It's had a new motor, new main driveshaft, 2 new solenoid water valves and a new front panel. It's a bit worse for wear but still works totally fine)

So
- With planned obsolescence in 20 years you have spent ((20y/5y) * $1000) = $4000
- With R2R in 20 years you have spent $1000 purchase + $1000 parts = $2000 max, probably less (assuming you want to fix it, you're still free to buy a new one if you want)

However I do agree that when R2R laws pass and companies are forced to sell spare parts they're going to raise their part prices to try and claw back the profit they lost from less sales. So it is important that any R2R law states that the parts must be "reasonably priced". No charging 50% of the retail price of the whole machine for a part that is only 5% of the BOM cost.
I would be totally fine if the replacement part price was its BOM cost scaled up to retail price and multiplied by 2.

I see this as the pendulum of history in action again. Back in the day when TVs started to become "single-chip", the technicians started to see the price of large parts (flyback transformer, voltage doublers, Yoke) become pretty high in an attempt to push to replace the entire set instead. Sure, back then there was still a great deal of second source parts but the pressure was on. This not only signaled how the times would become but also pushed less scrupulous technicians to blame everything on these parts, so they could apply a nice markup.

If the manufacturers sell decent quality products and charge for it due to the need to keep inventory of old parts, then so be it. At least it could put some deceleration to the waste culture that has permeated certain societies for the past 30+ years.

Another approach to getting R2R is having laws like in Germany where an appliance/device must be returned to the manufacturer when it is time to dispose of it. So that they have to deal with it's disposal.

If you make the cost of disposal expensive for the manufacturer they will naturally make the device last longer to save money.
Or at the very least, make the device easy to dissemble and recycle.

The only way forward with R2R is to make it less profitable to design things to fail instead of more profitable.

Even bigger is the current state of the car manufacturers planned obsolesce of their cars. One tiny example BMW have made the 3 series to be utter crap,
they figured that if  they replace a metal part inside the engine with a plastic they can charge you for a complete engine rebuild every 5000km (cant remember exact figure).
