That’s totally fair, and I think that taxes should be included as part of the prize in non cash prizes (and cash equivalent should include the taxes as well to avoid the incentive to make it difficult not to take the cash or for people to not take it).

And yeah, windfall taxation is tough because it includes large financial inheritance (which left unchecked results in nobility, at least according to the founders of my country), lotteries (which I see no reason not to tax like any other income), sentimental inheritance of small goods (like grandma’s jewelry), sentimental inheritance of real estate (yeah that needs taxed, but the taxation system should work with you on it), non sentimental inheritance of real estate (which will be claimed to be sentimental), and large winnings/gifts that while very nice may become a burden when taxes are applied. And the lines between all these are blurry enough that some people will be cheating it
