> But these requirements still ignore one of the biggest problems: the price of spare parts.
No, that is short-sighted.
The price of spare parts is the symptom. The root cause is that the part are highly specific to whatever they are going into, and there is a single supplier for them.
For repairs to be easy, things have to be made with generic parts that are available from multiple suppliers.
Not all parts have to be that way, just the ones likely to break, or ones that are expected to require replacement by design.
You're not going to get decent prices for spare parts, if you're vendor-locked, and there is no competition.
