What legal concept protects property owners from unauthorized use of their land?

The correct concept that protects property owners from unauthorized use of their land is property rights. Property rights encompass the legal rights that allow individuals to possess, use, and manage their property as they see fit, including the right to exclude others from using it. This protection is fundamental to real estate law, ensuring that property owners can control access to their land and enjoy their ownership without interference.

Property rights also provide a legal framework within which owners can seek remedies if their rights are infringed upon, such as through trespassing or other unauthorized usage. Essentially, this concept serves as the cornerstone of property law, ensuring that landowners have clear and enforceable rights regarding their property.

The other options do not specifically encapsulate this level of legal protection. Land use refers to the regulation and planning of land but doesn't inherently ensure protection against unauthorized use. Ownership rights are broader and may not address specific protections tied to unauthorized use. Privileged access is typically related to limited or special permissions granted to certain individuals rather than the blanket protection of a property owner's rights.
