It is true that currently Elon Musk continues to keep the price of Dogecoin at a low price and is waiting for the right time to increase the price of Dogecoin. In general, Dogecoin has the opportunity to increase its price to $1. But as you mentioned Elon Musk should consider everything before bringing the Dogecoin price to $1.
One thing is what Elon Musk wants and another (may be different) is what he gets. Remember that Musk is not the only Doge whale, and also remember that there are also many people waiting for Doge to reach a barrier (could be $1) to sell millions of coins, which would cause the price to drop rapidly. That's why I don't think Musk is going to "take" Doge to $1, most likely he'll do nothing and wait to see how the market continues. Musk must be very careful with his words on his social network, every day there are more critical voices denouncing his manipulations.
I think Elon, as a business executive wants to always be able to contribute to his company and, Doge is not a priority, in my opinion, for Elon, so that his company can make a profit. So I also believe that what you said is very true that Elon will never take Doge to $1, because he is not serious about Doge.
In the past, he manipulated what he had done and succeeded in bringing the dog up, but maybe not now, because many people already know that the behavior he has done is clearly not easy to carry out for the next action.
