Wow. Amazing. I am impressed. Many have been making some or all of these arguments for many years. A great overall article bring together a lot of issues.
And as long and as this great article is, there are so many things that he hasn't talked about. Like the absurd way NASA has already order hardware for flights that are literally 10 years away. So subcontractors are getting money now for these flights that will never happen.
The list of absurdities is to long to put in one article.
I remember people in space forums actually laughing at me because of my absurd believe the Falcon Heavy would launch before the SLS. That was years ago. I even made the argument in 2017 that Starship would launch before SLS, because SLS was so badly managed.
In fact, while that might be close for a first launch, before SLS launches a second time, Starship will have launched 10+ times at least. Before SLS launches a third time, Starship will have launched 50+ times.
This is because even if SLS launches at some point in 2022, it would not launch again until 2024 and at the very most once a year after that.
An internal way to call Starship at SpaceX, is Starship Launch System. They are either elite at trolling or to busy working to see how much of a burn that is.
Most interesting is, that even based on NASA own internal evaluation, SLS is a terrible design. In the end of the Shuttle area 100s of studies were done on launch vehicle, clearly pointing out the issues. Check out this post that gathers the evidence for this here:

The most important single thing is this:

This basically shows that what ended up being SLS (RAC1) was literally the worst possible design.
If you want to get an internal perspective for a SLS engineer (who believed in the project) see this talk from 2011:

A moon and mars base are not out of reach even if NASA current budget, if it is well spent.

I remember people in space forums laughing for the suggestion of the opposite. More, it's already in early 2000-s there was a strong opinion that NASA is wrong and commercial approach is the way to go, and birth of SpaceX was a logical development - after unfortunate closing of Beal Aerospace.
