Yes, by launching so many spacecrafts in space in order to make only one space mission sounds a bit as a pointless idea. I cannot even imagine the amount of resoursess will be taken for that mission.
It's easy to image the amount of resources when SpaceX's bid was half of Blue Origins, and delivers nearly 50 times more payload to the moon.
The reason is that SpaceX is using in-orbit fueling and a fully reusable launch system, while BO is relying on expensive old space launch systems without the cadence to support in-orbit refueling. Remember that Werner Von Braun actively preferred in-orbit assembly (the close cousin of in-orbit refueling) for the original moon landings, and only abandoned it because of the perceived risk of mastering assembling the lunar ship in their short time-line to the moon.
That was 60 years ago. In-orbit refueling is far simpler than actually assembly, and when mastered opens up the entire solar system to manned exploration. Starship is designed to have a high cadence, allowing a series of tanker flights to refuel the HLS in low earth orbit over a few weeks. If one tanker flight fails, no worries, another will be ready in a couple days. It's actually far lower risk than BO's plan which fails utterly if any launch fails.
NASA chose SpaceX because their design makes sense, and is the way out of the it's 50 years of handcuffs caused by expensive low cadence launch systems. Perhaps SpaceX will struggle to master in-orbit refueling leading to delays, but that risk is well worth taking. If NASA chose the Blue Origin lander all Artemis could become is a newer version of Apollo with an increase to 5 tons of payload , and likely fewer manned missions given it's expense. It's only going to be able to land a pair of astronauts restricted to a lunar day (at most 2 weeks, likely far less). They'd do similar moon walks, ride a simiilar moon buggy and return, same as Apollo.
SpaceX HLS has a 100 ton payload capacity, 20 times more! That's what in-orbit refueling gives you. It can land components to build a lunar base for dozens of astronauts, and the supplies , equipment and power storage necessary to last through lunar nights for a full time research presence lasting months or years. Not just short buggy rides, but exploring far across the lunar surface for hundreds of miles and beneath it for resources. Even visiting polar ice caps for ice.
We should absolutely wait to return to the moon until we have the capabilities to stay for the long run and do the exploration and experiments to answer all the scientific questions we've had since we left 50 years ago. Don't blow our limited funds on a pale Apollo clone and set back lunar exploration another decade.
