The belief that the scallop exists in order to manipulate the BCG with a thumb is one of those internet myths that just won't die, apparently.

The objection is that Eugene Stoner designed the rifle without the forward assist as it exists today. The first M16s brought into the military were purchased by the Air Force, and they did not have the forward assist. The statement that Eugene Stoner advised to put your thumb in the scallop on the bolt carrier and push forward to close the bolt has been around a lot longer than the internet. (yes, earlier I said bolt... while technically not correct, everyone on here knew what I meant... kinda like buffer tube vs receiver extension.)

You are correct, however, that much force is not necessary in a properly functioning rifle. If your action has become so sluggish that you have to use the the forward assist to seat a round, you have an issue that needs to be resolved.
