You would only feel ripped off because some dealerships say "No Haggle" and some do haggle. If every dealership has the same price for a specific car then literally by definition you cannot get ripped off.
You're also fixating too much on the meaning of MSRP. Before the car shortage MSRP was basically just a marketing number to anchor negotiations at a high number (except for cars in super high demand). Some automakers were notorious for deeply discounting below MSRP and some didn't discount much.
