I believe that your camp subconsciously (or maybe even consciously) believes that there is no tangible benefit from the taxes you pay.
That’s just not true. We just don’t think the government should be taxing more than necessary just because they can.
Everyone should have to pay for that benefit. Someone living off inheritance should not have government protection and benefits paid for by people with less money than him who actually have to work for a living.
Income taxes were already paid in that money. Money made from investing that money is subject to taxation. If the heir buys taxable goods or owns property, he will be paying taxes for that.
