As to to the question you answered, I could understand land value taxes, or some other forms of taxes that are actually based on the infrastructure cost for supporting your home. (And you could add exemptions/tiers for people who can't afford it, that's beside my point.) But property taxes seem nonsensical for exactly the reason you mention: that they depend on the value of the home (at whatever point) rather than on the cost of the infrastructure itself. Whether my home sells for $1 or $1M, my pipes and wires are going to act the same. And neither of those tells you anything about my means for payment - I could easily lose more money on a more expensive home.

Hot take: One possible compromise is limit prop 13 to a single property maybe two bed two baths for the owner and each adult state resident also gets this "credit"? I mean what the owner and every adult living in the household can help keep the property tax low but only for their own primary residence. but beyond that raise the property tax every year based on property value.
> What worries me is California refuses to raise property taxes
Sure, if you're trying to increase taxes somehow, then the proposal in your reply could be one way to do it, and it sounds less painful than increasing everybody's property taxes. That logic isn't what I have issues with, since you're just comparing different ways to do property taxes regarding primary residences. (This isn't to say I agree or disagree with it.)
> Raise property taxes because without it, your income tax will have no upper bound.
This is the part I took issue with. It appeared you were trying to motivate property tax increases by arguing income taxes are an obviously worse way to make up for them, but... why? I didn't understand the logic behind that, and that's what I was asking about. If I'm a policymaker trying to choose between increasing income and property taxes, why should I choose property taxes to be the one to increase?
But that's not relevant to why a policy maker should choose to raise property tax over income tax. You could argue both ways here - income taxes are straightforward because you can basically get your cut at the source of income but property taxes are good because you can't hide or take land with you to another state. And in general, I am not an expert on this or any matter but California is very lopsided with prop 13. I don't even live in California.
In the comment you just replied to, weren't they specifically saying this wouldn't apply to your primary residence?
