No more than any man you meet is a propertied member of the gentry and thereby deserving the title Mister, Monsieur or Herr. Almost all cultures have courtesy titles (more obvious in England where they still use titles for nobility, but most countries kept the title for respectable commoners even when they abolished fancier titles for nobility). Note that all person can use the title for “respectable commoners” even if they wouldn’t not have qualified (based on property ownership) in the past. To the extent we use “Ha-Rav Ha-Gaon” as a courtesy title for rabbanim is indicative that we still keep the concept of an aristocracy, albeit one based on Torah rather than wealth or military skill.
