Why would the noble might see himself as nearly the kings equal?

A noble might see himself as nearly the king's equal due to his significant land holdings, wealth, and influence within the realm, which grant him considerable power over local governance and military resources. Additionally, the noble's close ties to the royal family through marriage or loyalty may foster a sense of shared status. Furthermore, the nobility often held roles in the king's court, allowing them to participate in governance and decision-making, reinforcing their perceived equality. Lastly, the cultural and social norms of the time may have emphasized noble status as a vital component of the kingdom's hierarchy, blurring the lines between nobility and royalty.
