Turns out it is not straightforward to estimate what every asset in a country is worth.

So no adding together all wealth, but tax the value of real estate instead of the rental income. Tax market cap of public corporations instead of their profit. Tax cars, boats and business jets. Tax bonds and other securities on their value instead of revenue. Etc. All these ibdividual taxes are going to have issues to be sorted out before implementing, bit I argue that as individual taxes, the issues are way easier to solve than for one generic wealth tax.
Say you have a 100 acre farm[1] valued at $100 and produces $10 of goods annually. If you start taxing on the $100, no one is going to pay $100 for the farm once a wealth tax is implemented as now they are taking on tax liability that previously didn’t exist.
[1]for the sake of argument and illustration, were ignoring property taxes which are like wealth taxes.
Besides, for residential property, stemming the unsustainable increase in value is also a desireable goal to make it more affordable.
Corporate/bureaucratic governance is arguably more prone to doing the sorts of bloodless cost/benefit analysis that can push productivity, while smaller family farms might be more focused on just getting through the day-to-day work.
That plus a lot of productivity gains come from returns to scale and logistical capacity that you need to be at a certain size to realize. It's just out of reach for smaller entities.
Implementation dependent.
You may use "net worth": so if you have a $1,000,000 property but a $600,000 mortgage, your net worth $400K. Many of the proposals for the US start "higher" ($32M for Sanders, $50M for Warren) which probably would not hit a good portion of the population.
Yes. That's almost like magic. You get cheaper properties, the property tax revenue is used to reduce your other taxes so your net income does not decrease (on average, of course). So you actually get more money to spend otherwise than into your mortgage. Almost like alchemy. Turning taxes to wealth...
(Of course you can argue that western democracies are kleptocracies by default and all taxes just disappear to the pockets of the thieves and you get no benefit from them, but I personally do not consider that as a feasible starting point for a reasonable discussion)

They don’t soak the rich in quite as targeted a fashion though (aside from the estate taxes).
In the end, this loopholes and others lead to a very complex tax (thus high administrative costs) as well as a much lower tax base.
