No no, it's the same in the US and Canada. Wikipedia tells me it's around 1% for a £100,000 asset (in the UK). In Vancouver (Canada), I pay roughly 0.3%, so if anything the argument is stronger in Canada.
While you were _technically_ wrong that no one taxes on the entire value of the property, I think your point still stands, because the property tax rates are so low.
I believe that, in Canada, my trade-off looks like this:
On real estate, I'd pay a very low property tax (under half a percent?) on the principle, plus capital gains on the appreciation when I sell, plus income tax on revenue from the property.
On stocks, I'd pay some combination of capital gains on sale, and whatever the tax is on dividends. So the percentage on my income is higher, but it's only on the income.
The thing is, if you're gonna pay capital gains on the "wealth" (your definition) when you cash it out, the only reason it matters you're not getting taxed on the growth is that it compounds faster. So you get to ask yourself, which compounds faster, the non-realisable asset without tax, or the realisable one with tax.
