The "problem" is that people get what they pay for. The majority of consumers prioritize cost, so they get price-optimized devices that are difficult or impossible to repair.
When you prioritize, e.g., reliability or ease of service, that problem goes away, but now stuff costs more. Worth it for commercial/industrial products, but it tanks the consumer market.
My Kitchen-Aid mixer has had its sacrificial plastic gear replaced a few times because I keep overloading it with bread dough. It was designed to be repairable. My cheap Walmart TV, OTOH, is in the garage awaiting the annual electronics scrap pickup because although I know what the problem is, for $200 (about what I paid for the mixer 20 years ago) it simply isn't worth my time fixing it when I can buy a better one for the same price.
