What is the purpose of the wash sale rule?
'Note that "to keep an investor from lowering their tax bill" is not an explanation'. Well, yes it is. In fact  it is the only explanation. The rule plainly exists to prevent someone from realizing a loss when their economic situation remains unchanged before/after a sale. Now, you might say 'but I have suffered a loss, even if it is unrealized!' But, would you want to pay tax on unrealized gains? The tax system still caters to reducing the tax impact of investments, particularly capital investments. Part and parcel with the system of taxing gains only when realized, is that you can recognize losses only when realized. Are there other ways to 'artificially' reduce taxable income? Yes. But the goal of a good tax system should be to reduce those opportunities. Whether you agree that it is fair for the government to prevent this tax-saving opportunity, when others exist, is another question. But that is why the rule exists.
