By shifting the tax to property and away from income tax, you break that cycle.
Elon can have a Panama based LLC that doesn’t pay income tax, but that only means he avoids the $25K income tax and loses the $50K tax benefit.
The $10M property tax must still be paid, because it is levied on the properties.
He might be able to then subtract the $10M from his tax obligations in Panama, but for the country where the property resides (e.g. USA), that does not matter.
Unless it isn’t in his name, but someone who looks like a working Joe, then it doesn’t really matter.
That mode of attack won’t work.
Elon could take a risk by putting each property on the name of some homeless person and paying them an income so that the benefit matches the tax savings. It would avoid some tax, but it would also be quite easy for the homeless person to renege on the deal and keep (or sell) the property.
Trying to sue in court would massively backfire, since you’d have to admit in court that you were engaging in tax evasion.
And putting it on the name of some middle class homeowner will have all the same risks, without any tax benefit.
You’ll have to be more specific with how you see this failing.
Tax evasion with existing laws works predominantly because the agencies are underfunded and not equipped to track and follow the tax evasion schemes of the ultra rich, while they simultaneously lobby for that to stay that way or become even worse.
No matter the change of code, these issues will not go away, because there’s always some way to hide what you have, no matter the laws. While the current state of tax laws (no matter where) is very sub-optimal and heavily favors the rich, there is no way that a mere change in law would change that status whatsoever.
Since I personally do not evade taxes, I couldn’t tell you all the loop holes some high powered, high paid professional would find in your proposed scheme, so my assumptions are pretty low level.
Your proposal hinges on even knowing what they own. That’s already heavily obfuscated beyond some prestige projects they like to flaunt. I don’t think that it would be feasible to enforce finding and knowing what they own, because it’s already hidden in layers and layers of proxies, including non-profits, charities, etc.
