Regarding private property and how important it is to freedom, Locke said that if private property rights and protections don't exist, then the incentive for an industrious person (to develop and improve it) is destroyed. Marauding bands can then confiscate property and goods by force, meaning people will be forced to remain at a bare subsistence level because they'll believe that it does them no good to build something because someone will come along and take it away. So private property includes the idea that it belongs to you and is yours to protect, to develop and to use.
