Only in the short term. In the long term cars only last so long. Plastic starts to wear out from sunlight exposure (ozone?) in about 10 years. Spare parts go out off production so when something breaks it is live without. Some things just aren't worth fixing. Sure it is possible to fix anything, but the labor is too high in general. Collectors sometimes pay $100,000 to restore an old care to brand new, realistically if the assembly line still existed the car would be about $8,000 (of course it wouldn't meet modern standards)

The current new car problems mean some people will be keeping old cars running a bit longer than normal, but all those cars are headed for scrap eventually. Eventually everyone will be jumping to newer cars.
