It depends on how you define "easy".

I have a feeling that if I took all the time and energy I've put into studying and working with computers my entire life and chose to put all that time and energy into studying and working with business concepts instead, I'd be able to run a business, possibly even a Fortune 500 one.

Alas I didn't spend all that time and energy on business, so I can't run a Fortune 500 company, but alternate universe me might.

Those are essentially solved problems for which you don't need to reinvent the wheel and can copy what any successful small or medium business does.
