The problem isn't really petroleum. We have more than enough petroleum for straws. And the carbon in paraffin is not in the atmosphere, which is good.
The problem with plastic straws, if you believe their opponents (whose claims I have not evaluated), is that they are persistent pollutants that harm animals. If paraffin-waxed paper straws are not, that's an improvement, petroleum or no.
