Very well, In a system with no property tax, there would be no disincentive to [ synonyms: stockpile, store, store up, stock up on, put aside, put by, lay by, lay up, set aside, stow away, buy up; cache, amass, collect, save, gather, garner, accumulate, squirrel away, put aside for a rainy day; informalstash away, salt away
"they hoarded rations" ] please choose the preferred term which you regard as "unloaded". (synonyms courtesy of Google's dictionary).
If you get off on seeing people's wealth seized by force and redistributed,
That's all in your head of course.
Now, if you want to get to basics and discuss the pros and cons of allowing private ownership of what is called "real property" (basically land) in the first place, that is fair game.
OK, at the risk of this whole thing spiraling badly down the drain like my last back-n-forth with a libertarian, I'll bite.
Pro: Once you have the land, you don't have to worry about the government taking it away.
Con: Since you aren't paying property taxes, I see two possibilities: 1. The government gets the money some other way. 1a. Good for you, if you don't get caught up in the "some other way". 1b. Bad or neutral, depending on how expensive and/or inconvenient the "some other way" tax is. 2. The government doesn't provide the services customarily supported by property tax (e.g, schools, police).
Situation 2 is regarded as ideal by some people, and that's where I have a bone to pick. Why? Because if you don't pay the government tax, you pay what might be called the "natural tax" on the property. What's that? It's the cost of defending the land YOURSELF. IMHO, it tends to be much more expensive for most of us. It requires specialized skills most of us don't have--gunslinging, etc. Of course there are people willing to step in and do that for you. One of the most recognized organizations on the planet arose under just such a situation, where people were having a hard time defending their olive groves. This was in Sicily. I think you know where this is headed.
So, long story short, to paraphrase something often said about Unix: "Those who fail to understand government are doomed to reinvent it--poorly".
