First, saying that value of property is a good indicator of wealth is largely true. But the converse isnt true. Wealthy people dont always own real estate. So overall, its not a good indicator.
All taxes are "takings". Its just how they work. The government comes in, and takes money from you because they say you owe it. It sucks, but thats reality. So, the issue isnt "will we be taxed", its "whats the most fair tax". An income tax inhibits upward movement. A flat tax lets the rich off way too easy, while disproportionately effecting the poor.
That leaves us with basically a consumption tax and/or a wealth tax. I prefer the combination of both I discussed earlier. If you tax consumption only, then people may be hesitant to spend and therefore effecting the economy. But when you accompany that with the alternative wealth tax, it would prevent the wealthy from just sitting on their cash.
This would allow upward mobility. It proportionally effect all economic classes. It would promote spending, which would help boost the economy. It would remove capital gains, which would promote investment into companies (both public and private) and real estate.
Taxes suck. But since we will be taxed, this is the most fair I can think of.
