Well that's not your choice to make, that's how taxation works. The government choose how to manage and spend a portion of your money. Do you think your opinion matters in deciding if a hospital should be built? Or if we should pay for a new vaccine? No, because you don't know anything about those things. And neither do I.

So yes, I will take your money and build my big experiment, and I don't feel bad about it, because I am the expert.
