Why wasn't Harry sent to either a lightsided wizarding family or a muggle family?

John:
But what protection did the blood wards really give?  If it can't 
protect him from the darkest of creatures (Dementors) why would it 
be able to protect him from Voldemort?

Harry would've defeated Quirrel/LV in PS and in OoTP whether he 
lived with the Dursleys or not.  The blood wards should've stopped 
Voldemort from possessing him in the first place if they worked 
against him, which either points to the wards now being completely 
useless (Or in other words, why is he still with the Dursleys after 
GoF?) or them NEVER having worked against him, which seems to be the 
case after the DoM incident.  Harry's love for others was what drove 
off Voldemort from possessing him and IMO is what prevented Quirrel 
from touching him, not the blood wards.
