Why everything has to be money is because money is the commodity which runs to entire globe. Without money, there is nothing. Coinbase is a good exchange as well as wallet. Some of these coins mentioned by OP getting listed on coinbase means they would gradually create some more dense demand and would also experience some pump once they are listed onto coinbase.

No doubt that the coinbase might have charged huge listing fees for those coins and that is the reason why much of the coins never get listed onto some better exchanges. They can't afford to pay the listing fees. But in this case, the coins have already payed the listing fees which might also redirect us that they have excess funds available for the development of the coin which might surely be a plus point for their investors to trust onto those coins.
