As you can see from the discussion, there is a mod to override the restrictions of the portal. As for the argument whether or not to use it I find to be a matter of what constitutes "fun" for you. And this is the case for any mod or cheat on might use.

People need to understand that what makes the game more fun is going to be different for different people. I myself use mods, but not the portal cheat mod. For me the game would be too easy and there would be little reason for using ships. I like a game which is challenging but not too tedious. The mods allow me to tweak it to my liking.

For me it's not challenging enough without using ships. But I do use the ValheimRaft mod to make ships which are more functional.
