Cost is different from price.
The price of the computer you like may be high. The cost of buying a cheaper one could be that it crashes right when you are working on a critical project.
The price of the car you like may be high. The cost of buying a cheaper one could be that your car breaks down in the middle of nowhere and you miss an important meeting.
You can always buy a cheaper computer or car, hire a cheaper designer, or use a cheaper software, but you should be away of the potential cost of doing that.
As a creator, the price of your services may be high, but it won't be high enough compared to the cost of a cheaper alternative.
Once you understand the magnitude of potential costs, you shouldn't be too worried about charging or paying a higher price for better and more reliable products and services.
