You guess it is? Starship's other HLS competitor, the SLS, definitely is.
$30,000,000,000 in taxpayer money for one rocket launch that was 6 years late. Over 6 times what it is estimated that SpaceX has spent on the entire Starship program. I'm guessing they have an interior mockup somewhere, though.

One of the SLS mobile launch platforms was originally contracted to cost $343,000,000 and be completed in 2023. It is now estimated to cost $2.7 billion and not be ready until 2027. But do go on about Musk and the Starship program.
A contract to build a second mobile launch platform for the Space Launch System could end up costing NASA more than six times its original value.
