There's also no fundamental reason for the state to institute any form of estate tax; on the contrary, I specified it goes against our usual federal regime of taxing value as it's moved rather than value at rest. If anything, I'd question why you believe there's some inherent reason or right to have any form of estate tax, let alone to the point one forces liquidation of assets. One form of taxation can be more or less just than another and it's much easier to make the moral case for using force to collect a portion of value moved through government infrastructure (banking system, roads, ports, etc.) than something that remains unsold.

I didn't say taxation is theft and would rather you didn't put words in my mouth. You're assuming I'm against any form of taxation whatsoever on a moral basis, which isn't actually true. I think there are values reasons (most of us actually like the idea of a family business staying in a family, not getting sold to private equity) and moral reasons why we should continue resetting the tax basis of inherited assets. As a compromise position, I think it would be more reasonable for you to suggest removing the stepped-up basis but not counting inheritance as a taxable event.
