I don't care if a rich person buys a yacht or not, it's their money and after they've paid the tax they can do whatever they want. The wealthier you are you should pay more tax regardless of how you use the money. Consumption taxes just make it harder for regular people to afford things they want; the wealthy won't care that a luxury bag with 1000% profit margin has an extra 10% tax on top.

There's already exemptions for both income and estate tax for donations to charities or governments to benefit society. It's possible to set up a private foundation, with some additional guardrails to prevent abuse, if you want to give the money directly to people that need it.
