[General] you are not the only pebble on the beach = you ate not the only one in the world

[vil]

Dear teachers,

Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following sentence?

Though as an old Republican I have no respect for the Majesty as a King. I have a great respect for him as a Strong Man. But he is not the only pebble on the beach. Why not have done with the superstition of monarchy, and bring the British Commonwealth into line with all the other great Powers today as a republic?

you are not the only pebble on the beach = you ate not the only one in the world

Thank you for your efforts.

Regards,

V.

Yes, it is saying that there are many other options to consider or choose from.

A more current [no pun intended] way to say the same thing would be "there are plenty of other fish in the ocean".
