Why should I crate train my dog when he is so good for me already?

I adopted a 6month shepherd/lab mix last week and we brought him home and immediately started crate training him. The first few times he walked right in to get his "treat." I give him a kong with frozen peanut butter when he goes in the crate and that is the only time he gets his kong. He only whines and barks a little. Now he doesn't want to get in his crate at all. He sees me pull the kong out of the freezer and goes running to the other room. I sit down next to his crate and call him over to get a treat. He usually comes over and plops into the lap and gives me lots of kisses because he just wants to be next to me all the time. I now lure him into the crate with a small milkbone, but usually have to give him a little nudge to get in. I know you aren't supposed to push or drag them in, but he doesn't want to go in! He is so good all day. Chewed an electrical cord the first day we had him, but hasn't touched them since. He doesn't go on the furniture, or chew anything but his chew toys. He follows me around all day and falls asleep at my feet sometimes under the table where I do my school work. I hate putting him in the crate when I am there because he is in there all morning when I'm at class and all night to sleep. I don't want him to have to go in when I'm home! Does this dog sound like he is good enough to not be trained? Or should I stay with it because he is still so young and I've only had him for a week?
