And they believed him without being announced by someone they recognize? Draining the stone isn't necessarily going to prove he's the crown prince.

If you let a Queen rule the country will fall like England. Countries need king, and from ROYAL lineage.

@prothy like @Rift said, monarchial governments are historically patriarchal, even forgoing immediate female descendants if a male relative is available. From what we know, this country is a patriarchal monarchy. In some cases, Crown Prince can also be considered more important than his mother the Queen.
