I was pointing to the argument that "you didn't do anything to make it happen. Only right that excess value goes back to society and reduces the tax burden of the working class."
Sounds like Obama's "If you’ve got a business, you didn't build that" argument (though Obama might have just screwed up the words, or maybe he simply had a Kinsley gaffe, aka a Freudian Slip).
The land owner DID work for it. He BOUGHT that land (and also the option that it could go up, or down, in value) with the sweat of his hard earned work or savings, or that of their family or business partners.
OP's wording states that he would favor confiscating value generated by the acquisition if such value happened because the market's perceived value increased.
It's basically a communist wealth redistribution logic.
My point is that if someone were to offer $1M for OP's "bengarcia.dev" domain, that OP would not send $999,988 ($1M minus $12 bucks of registration) to the Federal Government.
Yes Ben, The US Government IS READY TO TAKE YOUR GIFT!
