There is no price too high for knowledge.
Every human action (and inaction) is a choice between options. Quite often from an incalculably large pool of options and trees.
Choosing to pay for a big science project now is choosing not to do a gazillion combinations of other large and small searches for knowledge. Are you really so confident you know the best course of action?
Obviously, there are additional problems:
- You are forcibly depriving individuals of their private property for your pet project. This is immoral.
- There are other goals than knowledge. Worthy goals, which other people may have a higher preference for.
- There's also obviously a time-preference calculation. Do you want to spend your resources on 10 units of knowledge achieved immediately, or do you spend your resources on the promise of 100 units of knowledge 8 years from now? The obvious answer is the second choice if you ignore time preference. However we have time preference for a reason, what if the knowledge in option two never materializes?
- If the wrong decision is made, do you stay the course or change directions?
Quickly these decision trees exceed the abilities of any central planner. Funny enough, this is why socialism and communism always fail in the long run. It's almost impossible to central plan very complex systems efficiently and it is entirely impossible to central plan everyone's means for everyone's personal preferences and goals.
