I think it would be fair to keep paying for a car, house, bike, shoes, toilet, and fridge. If I'm still using such great products, why not reward the creators of them. But as a consumer I am also price conscious so if a competitor can offer an equivalent product for cheaper I will go with them.

There are arrangements where you continue to pay for cars and houses without owning them. They're called leases and rental agreements. They typically cost a lot less for the consumer than outright purchases and at the conclusion of the lease/rental term the consumer is free to return the car/house to its owner without compensation for depreciation or wear & tear (though car leases usually impose mileage restrictions and routine maintenance requirements).
