This has not been consistently true for me. Maybe for long-term stays (week+), but certainly not for for a day or two after adding in all of the cleaning fees, etc.
I traveled extensively in 2021 and routinely I can find weekend stays on Airbnb, for the entire place, between 250 to 350. Two star Hotels (la quinta, HIE, etc) routinely want 400-600+. It's total insanity.
Where are you traveling that hotel rooms are that expensive!? Up and down the US east coast, there are plenty of perfectly good two-queen-bed rooms for under $100 per night. I recently stayed in downtown Boston in a boutique hotel for $130/night and the surrounding hotels were all under $175/night.
