"instead of using $100,000+ radiation-hardened aerospace/defense grade chips"
Well, that makes perfect sense considering that both the spaceport infrastructure, and the booster need to do their calculation on the ground level instead of the highly radiated environment that is space. However, for the rockets themselves, which happen to reach that harsh environment, they may use more resilient and expensive hardware in the future, after passing over the current "let it splash in the Indian Ocean" development and testing phases.
