The $7500 existed only for other manufacturers. It had expired entirely for Tesla. No Tesla model was eligible for any more credits at that time and there was no particular reason to believe that Tesla would ever become eligible again in the future. Also, the credit back then did not directly reduce the price paid at purchase time the way it does today. I think it is fair to apply the credit when comparing to the announced price. Tesla certainly takes the credit into account when they set pricing and buyers account for it when purchasing. Also it was announced at the end of 2019 for 2021 and the inflation rate in 2019 was 1.8% so there's no way they accounted for 6% inflation. 4% at most.
