No surprise that you'd show up to shill for it.Your argument boils down to 'if it looks like an executive branch agency, then the Executive branch should have control over it' rather than accepting that Congress is free to set things up as it sees fit within the Constitutional constraints.
Hypothetically, if Congress passed legislation saying "it looks like an executive branch agency, the Executive branch should have control over it" you'd consider that a generally reasonable position all else equal?
If you concede that it looks like an executive agency then it actually seems quite proper that the executive control it.
