Re: ...and "blow" through a "whopping" $10bn in funding
It's 5% of 1% of the US GDP for one year...
Billions of ${currency} sound alot until you scale to a population.
Given the joint nature of the project we should be distributing that cost over a population of ~800 million people.
So that's ~$12.50/person over 25 years (or maybe over ten years for the duration of the science mission rather than the build process).
