Except for 'For Sale By Owner' homeowners (AKA as unrepresented sellers), Sellers who have their home listed will have an agent looking out for them.........so why not you, the Buyer? Shouldn't you have someone in your corner 'looking out for you'?

Sellers with their home listed have a Listing Agent, who is contractually bound to 1) make every effort to obtain the highest price for the home, and 2) exclusively negotiate favorably all terms and conditions for the Seller.
