GDP is flawed measure - unfortunately we lack a better one.
The aim is to maximise utility, but we cannot quantify utility, and cannot tell when it increases at the level higher than an individual. So we use GDP and then .... Goodhart's law.

Something like GDP - (Sickness, Mental Health Therapy, Fixing broken windows and flat tires... et. al.)
That still does not solve the underlying problem. The aim of an economy is to maximise utility (vaguely defined as happiness, satisfaction with life) or more meaningfully defined as an individual's preferences, The problem is that we cannot meaningfully aggregate this across individuals to maximise for the whole economy.
