The "free" federal tax filing service I use in Florida, makes their money by charging for state filings. It will add an additional hour or two of effort to every resident of the state, even if they are below the state income threshold which is quite an externality.
Also, I would be wary bragging about buying your goods in Oregon, you technically may owe WA use tax https://dor.wa.gov/taxes-rates/use-tax.
