What is a primary reason for having a power of attorney?

The primary reason for having a power of attorney is to allow someone to manage your finances if you become incapacitated. This legal document grants an individual the authority to make financial decisions on your behalf when you are unable to do so yourself, whether due to illness, injury, or any other reason affecting your capacity to manage your affairs. It ensures that your financial obligations are met and allows for transactions to be conducted in a timely manner, which can be crucial for maintaining financial stability during difficult circumstances.

The options that involve establishing a permanent estate plan, handling estate disputes in court, or preventing someone from making a will address different aspects of legal or financial planning and administration but do not capture the core function of a power of attorney, which is specifically related to appointing someone to act on your behalf in financial matters when you are unable to make those decisions yourself.
