You're bring a lot of energy that suggest to me this is a particular bone you have to pick. I agree econ can be a science. Sadly this meme doesn't dive into the sociological foundations that validate the possibility of a hypothetical world where econ is done properly and can become a science along side other social sciences; choosing instead to just critique the absurdity of economics as it is currently exists.

I guess economics is just a more robust field of science than biochem, pharmacology, clinical medicine, materials science, and psych, because that’s totally what the data means.

I think there are other issues with the paper that make me hesitant to take it's conclusions at face value.
