PROBLEM: "It is already Federal law not to have a weapon within 600 feet of a school or a day care center" 
.

Nope. 

(Though you're right about the ridiculousness of the patchwork, it only applies if the person KNOWS there's a school too close to where s/he is.) 

.
First off, it's 1000' (apx. 3 blocks), including on the property & in the buildings, though there are exceptions... including having a CCL from the state in which the school sits. 

. 
Secondly, that federal "gun-free" school zone law only applies to grades 1-12, not day care centers, not kindergartens, not colleges. 
.

For the actual federal law giving the definitions, see 18USC921 (25) and (26) here:

For the federal "gun-free" school zone law itself, see 18USC922(q)(2):
