create a law mandating all advertised prices of goods and services be inclusive of all applicable taxes.

It is time for all advertised or published prices include all applicable sales taxes. A $2.50 slice of Pizza should cost $2.50 not $2.89 or something else. Most of the world does this already. In order to make the playing field level this must be required of all businesses otherwise those who choose to do it will be at a disadvantage when consumers are comparing prices.
