Yeah physics is also not a real science. Newton just made a lot of laws up and everyone decided to go with it (and could even launch satelites with it!), and it has been proven he was wrong in certain scenarios (relativity in speeds near light). /s
The economy is complicated, people create models to try and describe it, they aren’t perfect and don’t work for all cases. That doesn’t make it a fake science.
If it is studied with the same rigor that other (social) sciences are, I see no reason to deny it. (And i think it is)
