Without property rights, the other rights would become meaningless, because, over the long term, they could not be defended. A man bereft of property, or dependent on the government for property, is ill-equiped to defend his right to speak, worship, peacably assemble, and be secure from unreasonable search and seizure.
Its much worse than you think.
Several generations have completely given over their property rights to practically anyone.
The popularity of Facebook and Google are perfect examples.
People have not been properly schooled to understand that your personal information is your property too.
