And also, there's certainly places and situations where you do want to spend tens of thousands on PLCs, buttons and wiring.

But not all of it needs this level, quality or insurance. A factory, farm, supermarket, stage, etc, is filled with tech. Many of it critical for operation, but just as many is non-critical. And either this "non critical" must then be acquired with the same level of quality, insurance and costs as the critical. Or it's simply not available - likely because there's no demand for it at this price point.
