What would be the challenge to affirm, the right to take a tax deduction on purely intrastate commerce? The feds might like that case because it furtheraffirms their ability to tax anyway they seem fit on purely intrastate commerce too.

I think it relies on you taking the deductions to begin with and the IRS saying “heyyy waaait a minute, some of these deductions in the trafficking of scheduled substances violate Section 230E, the others good though!” Which .. isnt really that farfetched but aside from the tax court case you could be facing a defrauding the US government criminal charge, and other stuff actual lawyers might be more aware of.
