Elon Musk has six children. Bezos has four. Bill Gates and Steve Jobs both have kids (though Jobs was a pretty poor parent by all accounts). Most of the CEOs, executives, and other powerful, driven people I know have children.

I think your instincts are off and you are trying to explain to yourself why it is ok (and really, superior) that you don't want kids. In reality, you needn't explain it to anyone, you simply don't want to.
