We should rather agree that the bitcoin price of such a node should be stable.

EDIT: It also does not really make sense to 'serve' high high end miners with a Rasp PI - that does note really fit into a 'stable' hardware picture to me, rather shows that there might be (hard- AND software) bottlenecks for high end scaling ?
i do not agree that we should stick to Raspi specs.. but i do not believe the fud of $20k servers this next decade
same as
i do not agree that we should stick to 1mb base blocks... but i do not believe the fud of "gigabytes by midnight"
normal natural growth, where obviously nodes that cant handle it wont run the software and as such new rules wont activate due to consensus.
the issues arise is when bypassing consensus and then go fud extremes to blame others when things dont go to plan by those trying to force an issue
dynamics can work and keep things on a healthy natural growth, without devs or corporations control and without things going to extremes or stalling due to fear/fud
