That makes sense. The only thing I'd argue is that you're comparing standalone systems vs a full integration. The value from Control4 does not come from a simple setup with a single use case (i.e. lighting control), the value comes from the full home use case. So lighting, audio, video, cameras, intercom, garage, gate, thermostat, and others when combined. That also means a standard install makes zero sense to be small. It is a better idea to use a different product to save on cost, but they don't integrate into the full ecosystem as well.
As for Ubiquiti, sure they are cheap, but
