Final answer:
Ownership is defined by property rights, not by the need for continuous payments or maintenance. Property rights determine who is responsible for maintaining property and reducing risks.
Step-by-step explanation:
Ownership is defined by property rights, which are the legal rights of ownership on which others are not allowed to infringe without paying compensation. It is not defined by the need for continuous payments or maintenance. For example, even if a homeowner is paying off a mortgage or property taxes, they still have property rights and can exercise control over their property.
The concept of property rights is important in determining who is responsible for the costs associated with maintaining and reducing risk. If a well-defined legal responsibility is assigned to either party, that party will seek out and pay for the least costly method of reducing the risk. For instance, if a farmer has a property right not to have their field burned, they will take measures to prevent fires, or if a railroad has a property right to run trains on its tracks, it will invest in safety measures to avoid incidents.
In conclusion, ownership is determined by property rights, which grant individuals the legal rights of ownership and control over their property. The need for continuous payments or maintenance does not negate one's property rights or ownership status.
