Level 5 spell + portals in important locations in which the spell has been casted every day for one year doesn't make it a "quite normal" way of traveling, especially in such a small area in the middle of nowhere.
Ever played other video games, read books, look at films in the Forgotten Realms ? My knowledge maye not be fully updated but I guess no one would say that it's a "quite normal" way of traveling in the FR but you.
Teleportation also exist in The Witcher (and many other universe) without being a common way of traveling.
