Well we do this for many situations where it does actually matter. Drivers license requirements force people to "do it right" the first time, you can't (legally) fuck around driving a car on public roads until you eventually figure it out. Airline pilots and nuclear power plant operators have even stricter requirements. Licensing and training has a very real cost as well of course, and for many topics the cost of forcing everyone to get a license would outstrip the benefits. So you either have to spend on training, or you have to spend to fix the mistakes of untrained people, or a mix of both. There is no way to bring the waste to zero.
