I tend to agree, though there are possible solutions that are technically simpler (if less ambitious) than either Starship or Blue Moon, while not even requiring SLS. Though it is probably too late now to try those. It's all the more surprising that Lockheed Martin still tries to offer an alternative solution:
> In a statement to Reuters, Bob Behnken, vice president of Exploration and Technology Strategy at Lockheed Martin's space unit, said the company this year has been conducting "significant technical and programmatic analysis for human lunar landers."
> "We have been working with a cross-industry team of companies and together we are looking forward to addressing Secretary Duffy's request to meet our country’s lunar objectives," said Behnken, a retired NASA astronaut.

But their offer would likely be very expensive, and it would be very questionable whether it can be faster than Starship HLS. So I don't think they will receive a contract.
