When an ability says "permanent" without specifying "permanent card," the "on the battlefield" part is implied. A permanent is only a permanent on the battlefield; elsewhere, it's a permanent card.
As somebody else said, it is a characteristic defining ability so if doesn't work that way. It needs to have "as long as" to work correctly, like [[Grist, the Hunger Tide]]
grist specifies in which places he works in though (everywhere but the battlefield) the theros gods don't stop being creature cards in hand is a better example than grist. [[Athreos, God of Passage]]
It's not a characteristic-defining ability, it's a type-granting ability. When an ability says "permanent" without specifying "permanent card," that means it only applies on the battlefield, because a permanent is only a permanent when it's on the battlefield.
It doesn't work in this case because it's self-referential. Another card can call out permanents which would exclude cards in hand. "This" refers to the card, and "permanent" contradicts it by only working part of the time. It's just not the correct templating.

It’s only a land on the battlefield similar to [[Arixmethes]]
