x86? Why ever

What does the cost matter when the Federal Reserve can print infinite money?

On a long enough timeline whatever the cost of the mission- it will be more expensive to buy a loaf of bread.

What does a 'dollar' cost?

Cost to orbit is about $10,000/lb .

Lego figures weight about 2 grams or .0045 lb.

That yields a cost of $45 per figure to orbit.

Moving them from orbit to Jupiter will cost almost nothing, although it will slow the trip slightly. Rounding up for the additional costs to Jupiter, gives an approximate cost of ~$150.
