There are such restrictions in place, which some low-lifes simply ignore. Other times, the local officials completely reinterpet laws regarding land use to legitimatize their activites. In rare circumstances, court cases go all the way to the State Council, and the victims got ruled in favour as result. In subsequent land garbs though, the local officals just make extra sure that the central government won't have any knowledge on the situation (cover-up).By greater economic freedom, I mean that there ought to be restrictions on the monopoly of government power that is widely used to force unwilling parties into detrimental transactions. For example, the local governments often use their power to grab land at extremely low prices from poor farmers, and a lot of them also tax the heck out of these poor people, thus in effect, taking away their economic freedom to use their money for the most productive causes. I do not see any way that restrictions placed on officials for these kinds of low-life activities would in any way harm CCP's control. On the contrary, I think that if these kinds of restriction are not in place in the foreseeable future, there will be enough political and social instability fostered by social discontent that CCP's power to rule will be directly and seriously challenged.
As you can see, restrictions are in place. But when they can't be properly enforced, they might as well be useless.
And on the subject of economic freedom, there are plenty of people setting up "factories" in their tiny court yard and got away from paying taxes. They are obviously pretty free in setting up business, and aren't controlled. Unfortunately, these are lost of legimate tax revenues, not to mention that the quality of the products from these places are extremely problematic, which endanger the health and safety of the publics. And you are still expecting to see less control? When will less control be less control?Again, those are tremendous burdens on the economy of the country that you don't see, because no one reports on the amount of revenue that never materializes from these uncertainties.
