A home is for living in. A person has one body, therefore one home per person/family unit is an appropriate number. Corporations have no bodies, therefore they do not need homes.
Not only is rent robbery, but private property in itself has its origins in theft.
ITT: No one understands the benefits of renting over owning a home.
Well in theory it makes you more mobile (if you want/need to move for some reason): just give your landlord notice and move out. Whereas selling can take an indefinite amount of time.
This is called a risk investment. The risk is that nobody rents the place, in which case the landlord would lose the property.
As a renter, you have the freedom to call out that bet, but it's quite probable that somebody else will rent instead of you. Also, if the markets are efficient, it's almost 100% that you're not getting a better deal anywhere else for your place of residence.
