I totally agree and forgot to mention the separation of puppy and human.
Along with taking him places, you do need to make him be by himself. It teaches him that yes, he is part of the pack.. But it also shows him to respect you. Dogs that never leave people alone and are attached to the hip don't respect their people. Not allowing time to yourself is teaching the dog that he cannot live without you be his side. Not forcing the pup to cope with being alone will also develop separation anxiety.
