I may be in the minority here, but it's possible that there can be a scientific economics.

Sure you feel one way. Other people feel another.

But it's also possible the correct answer doesn't depend on your feelings but on falsifiable theories.

If you can come up with a scientifically falsifiable theory on the effectiveness of government regulation, there’s a Nobel Prize waiting for you. It’s hard for a lot of reasons, including that it’s almost impossible to create a true test and control treatment.

Macroeconomic theory relies on a lot of spherical cows. In theory I don’t disagree with you, but in practice we don’t have the tools (yet) to do this type of economics in a scientific/falsifiable way.

I don't think you can come up with a quality test for economic scenarios in a truly scientific way, many monopolies dominate for very different reasons, many industries have very different mechanics, and worse, regulations are often implemented in vastly different ways and often won't come out the way you'd like them to even if you have a perfect scientific answer to a given problem.

You can't guarantee or even approximate a given input and output for a scenario like this.

I'm not sure I quite understand, but it's certainly possible the equations that govern economics are sensitive to initial conditions. In that case we will never know enough to specify the initial consitions entirely.

But we also don't need to specify initial conditions exactly to do science.

I'm less convinced that the equations themselves are unknowable.

We also won't be able to specify the outcome precisely even if we somehow had a guaranteed outcome in mind.

Politicians will screw up the implementation, businesses will engineer around it and the alternative solution might ultimately come out to be a better one in practice than in theory.

Trying to define economics by simple equations which you expect to define policy is a lost cause.

Look up Hayek on the pretense of knowledge in economics.

Hayek isn't particularly well regarded as an economist, even among those that love his politics.

See e.g. Milton Friedman's comments about how flawed Hayek's economics are and how great Road to Serfdom is.

So my take on that speech is it's political rather than scientific.

In general I'm skeptical of arguments that something is unknowable unless they come with a rigorous proof or at least a well stated conjecture that has stood the test of time.
