Why did Robinson Crusoe use the words "king" and "lord" to describe himself on the island in Robinson Crusoe?

Since Crusoe
found himself to be alone, the only human on the island, he was able to do whatever he wished.
Realizing this, he considers himself to be the ruler of the island and the possessor of all the
resources present on it. His subjects are the cats and dog he rescued from the ship; the parrot
is a servant, since he was able to talk with Crusoe. In Crusoe's mind, they carried out the
proper rituals of English society and maintained the lifestyle to which he, as ruler of the
island, was entitled.

see how like a King I din'd too all
alone, attended by my Servants, Poll,...My Dog...sat always at my Right
Hand, and two Cats, one on one Side the Table, and one on the other,

Crusoe found comfort and some connection with the English society
from which he came by attempting to develop a familiar structure and society on the island; he
also enjoyed being able to place himself in the position of supreme power.
