united-states criminal-law death suicide sovereignty
What can person A not authorize person B to do which A can do on their own?
<p>In the US, there are many things a person has the right to do.  Regarding these things, what actions are legal for person A to do but which would be illegal for person B to do even if formally authorized by A?  Only one comes to mind:</p>

<p><a href="https://law.stackexchange.com/questions/25178">(How) Can Person A grant immunity to Person B for ending Person A&#39;s life?</a></p>

<p>Are there others? If specifics are needed, suppose the state is Oregon.</p>

<p><strong>Legal Representation</strong>: You have the right to represent yourself in a legal proceeding, but you cannot assign that right to anyone that you choose, only to certain approved individuals. </p>

<p><strong>Vote</strong>: You can vote, and you cannot assign that right to another. </p>

<p><strong>Jail Sentence</strong>: You can (indeed must) serve a jail sentence or be executed for a capital crime yourself, but you cannot allow another person to do that on your behalf. </p>

<p><strong>Military Draft</strong>: When we had the draft (most recently), you could not authorize another person to serve in your stead. </p>

<p><strong>Marriage</strong>: You can marry your neighbor's sister (if she is not related to you), but you cannot transfer that right to your neighbor (who is the brother of the intended bride). </p>

<p>These <em>are</em> different things from committing suicide, but it's not clear exactly what concept of exclusive sovereignty you're getting at. </p>

<p>Similar to @user6726 item about legal representation,</p>

<p><strong>Building Trades</strong>: Person A can do various carpentry, electrical and plumbing work on the house they own and reside in, but are restricted in their choice of person B to do it for them.  </p>

<p><strong>Healthcare</strong>: Same with healthcare, I am guessing.  Person A can slice off their own [skin tag] or sew up their wound, or take medicines, but outside of certain emergency situations (e.g. anaphylaxis), are restricted in their choice of B for medical procedures.</p>
