If we would decide to tax raw materials instead of labour and income, repair would make economic sense again. Raw material usage is not sustainable as the resources are finite. Labour on the other hand is very sustainable, given enough time the supply of labour is infinite and usage of labour is sustainable. What we tax and what not is not a given, but something that can and should be revised to gnudge the world into better shape. Even though I greatly sympasize with the right to repair, as long as it is uneconomical to do repairs due to incentives (taxation) making it so, we are not really addressing the root cause and one could argue that this repair day is distracting attention from the real issues
