I'm not sure how you can conclude that for any infrastructure project, complexity scales sublinearly. This feels true in software, but not real world matters IMO.
Think of all of the politics & hard choices involved, for instance, in displacing people vs. bending over backwards to accommodate them with the California high speed rail project.
Total project complexity isn’t the relevant metric here, a project with 100x the budget has more people managing it any many decisions don’t make it to the top.
Also, if a 2x as complex a thing takes 10x the budget then that scaling is already part of the budget figure.
I read both your links, and I saw literally nothing about "forcing" anyone off the streets. What I did see was a lot about peoples' right to shelter in NYC, which does not imply that someone couldn't freely choose to live on the streets. In other words, nobody needs to live on the streets, but it doesn't look like anyone's necessarily prohibited from doing so, either.
That deal was announced last October, but does not seem to be working yet. Or even in test. Searching the Audius API docs returns zero references to Solana.
