You can’t convince (almost all) consumers to spend money on something that they do not want.
You can, but it’s easier to convince them to want something that they don’t need or is actively harmful.
You can make them want things. Ad money is what powers some of the most successful companies.
That's the entire point of the trillion dollar advertising industry
Car insurance. Low flow showerheads. Fuel-inefficient vehicles. Electric dryers. Electric stoves. Appliances that don’t last. Lawn care.
Taxes. Social Security.
The list is gigantic. Your claim could not be more false.
Of course you can. And for the rest, you just discontinue the product they want so they have no choice.
