Missing a big point
Hate to be the NIT, but local jurisdictions in the US are NOT required to use GAAP. The argument should be made that they should, but that's somewhat skipped here.
I think a stronger case could be made by drilling down into the differences between (1) Those that do and elect no exceptions to GAAP, (2) Those that do but take exceptions, and (3) Those that don't use GAAP. Then (use the subsidized AI if you like!) to correlate where the biggest tax deals are made. I bet Deloitte does studies on where the most favorable tax jurisdictions are for AI DCs!
From this report linked below, titled "Financial Reporting Framework Requirements for State and Local Governments: Evaluating GAAP Choice":
"there is no single authority that requires that GAAP be utilized. Rather, each state can decide to require a financial reporting framework (either GAAP or an alternative) or allow its local governments
choice in selecting a framework"
