Aragorn was already leading the Company.

You followed my lead almost to disaster in the snow, and have said no word of blame.

Also Aragorn said he would follow Gandalf .

"But the question is: who will follow me, if I lead you there?"

"I will," said Gimli eagerly.

"I will," said Aragorn heavily.

Yes, reluctantly, and then fortelling his possible doom in Moria. As though he is saying, fine I will follow you this time into Moria, but don't blame anyone but yourself if you perish. This last warning did not change Gandalf's mind, and the Ring went into the unknown darkness of Moria. Aragorn decided against arresting the situation and claiming the leadership at an opportune moment, when most of the Company would have possibly sided with him so as to not go through Moria.
