Land and property not good because you can not take it with you or move from another place to another in some case the car would be even better asset to have.
I like land because of freedom it provides. You can build shelter over it, grow food on it, if you want to move from one place to another — you can always sell it.
land is not freedom
a. property taxes/ maintenance costs means its an ongoing costs, these days you even get fined by local government for not maintaining property
b. your not free to build anything, you need permits to do things these days, the only thing you dont need permits for is to paint the internal walls. c. externally like building extensions, groundwork, new builds even external paint usually needs permission from state or a HOA
d. if you wanted to change the purpose from agricultural to residential you need permit. or the opposite way round
e. as for selling it, thats not a guarantee. land can lay unsold for months/years or become valueless if the area becomes a ghosttown
Your points are country dependent, here in India agricultural land needs no maintenance, no property taxes on it, and selling the farmed produce does not incur taxes either.
Regarding house, one who owns the agricultural land is free to build house on it along with whatever one wants to do to the house, but note that there is term FSI (Floor Space Index) here which implies how much of total land area can be used for construction, and this FSI differs from state to state, unless you want more construction than permitted to agricultural land owners, only then you have to convert agricultural to residential.
On selling, where I live there is rapid development, property prices have significantly increased in last 5 years, so at least here, if one were to sell and preferably give some discount, it'd get sold pretty fast.
Above answers are based on my 'afaik' knowledge, if anyone is sound in Indian property affairs, and have something to correct, feel free to do so, I'd be glad.
