Most states have property taxes, so we do have forms of unrealized capital gainz.. especially since many states will update the value of your property from time to time based on their own assessments and then the amount of tax that you pay (many time annually) is based on such assessment.. which also is part of the reason that people will call themselves cashflow poor and capital rich.. but then they may end up having to start to get loans against their house just to keep paying taxes and of course their other living expenses that keep going up faster than their income (especially once they are on a fixed income). Of course, we know that the robbery of the people is subtle with the ongoing debasement of the dollar (and other fiat) and the various other ways that property values are assessed, and assessments are made regarding how much of a cut (if any?) might need to go to either the federal government or state/local governments.
I would argue that those are not taxes on unrealized gains. You are charged an annual tax for owning a property and it goes up with inflation but if they were taxes on unrealized gains in the tax bill there would have to be a subtraction between the estimated value of your property two years ago, and the previous year. So for this 2025 you would have something like this:
Estimated 2023 value: $600K
Estimated 2024 value: $700K
Gain: $100K
And on that $100K you would be taxed, but I am sure that is not the case and it will be like in Europe, that depending on the value of your property (not the supposed gain), and the place where you live and the taxes of the government there they tax the property to theoretically finance public services like infrastructures.
You seem to be merely talking about how it is framed, and property tax can be framed as unrealized gain rather than merely being paying for government services in the area (location). It does makes some sense since it is geographically bound, as compared with bitcoin holdings would be tied to the owner (whoever controls the private keys), which may not be geographically tied down. even though we claim to be associated with locals and/or nations..partly by force since labor/people seem to have more restrictions on moving than capital.. even though with tariff disputes, there are questions regarding the movement of goods and trying to incentivize and/or disincentivize the location of capital. I know I am meandering, even though I am not going to move off of my point that property tax can still be considered as a form of unrealized gain.. even if it is expressed in terms of value rather than gain..
Maybe they ran out of cash? No matter how hard MicroStrategy tries (now rebranded to Strategy), it will never be able to accumulate most of the circulating supply. The rest will be laid in the hands of the people. And for a good reason. We don't want Bitcoin to become centralized. Do we?
Why does it matters what "we" want? Some people, governments and/or institutions have heard about bitcoin and they are not being quiet about bitcoin's value proposition in terms of buying it up.
This has become every man, woman, and/or child for himself, while companies, governments and status quo rich people start to suck up as much of the BTC as they are able to suck up, and sure, there are some governments, companies and status quo rich people who have not yet figured it out, and sure no real problem for any of us who believe that we largely front-run the recent arrival BIG players, yet those who have not gotten any BTC or have barely started to buy bitcoin (no coiners and low coiners), they are going to have to buy at higher prices, since it can take a long-ass time to build up a decently-sized BTC stash, whether they start buying BTC now (such as, as soon as possible), or if they choose to wait and buy BTC later... yes.. later at a likely higher price, and sure some won't buy BTC and will die as no coiners, but others are going to figure it out, even though it may well take some time for "everyone" to realize that they should get some corn in case it catches on.
Hopefully, you have gotten enough Abiky, especially since you have been around these here parts nearly as long as me.
