That is because there is not a cost for the disposal of the broken vacuum. Imagine if we paid by the weight of our trash. Some of the right to repair laws are trying to change that by requiring replacement parts be available to purchase. https://www.repair.org/know-your-rights

I really like the idea of adding taxes (or subsidies) to make repairing things more economical than replacing them, when this is not the case already. It seems difficult to fairly decide how to do this, but charging by rubbish weight is at least objective and easily measurable.

It can be argued that all taxes and subsidies are "artificial distortions" of market value, but capitalism strongly encourages externalisation of costs -- "the cost of making X" is often severely underestimated by "the cost of running a machine to dig X out of the ground".
