To respond in a practical way to a likely troll post...
Point 1 the game would end service due to being unplayable on almost any system with modern high speed home internet. Maybe with a $3k+ PC and a T1 business line for just one internet connected device would this be possible in an MMO.
Point 2 the game would end service long before anyone hit level cap due to genocide of all enemies and people quit even faster than they quit FFXI in its early days at lvl ~13ish.
Point 3 like someone said... The enemies turn MRoe MAu'ra and MHHyur into bug like existences as it is also... Who better to tank rats squirrels ands ladybugs than someone who doesnt have to play dead just to get their shield in the right spot. Also this refutes dwarves in almost all their occurances in fantasy worlds.
Point 4 at some point youd realize that everyone lives on tap water raisins and hard boiled eggs and think... Thats nit a balanced diet for that rigorous a lifestyle and your immersion would die anyways.
Pseudo point 5ish having to repair your gear is a bill, paying for teleports is a bill, paying for transport paths is a bill, ranking up gcs is a bill... Tho i had rent in eq2 for housing but the auto demolish feature somewhat counters that need, as long as you can pay far in advance.

Tho i guess my rebuttals to point 3/4 were a bit of pure troll fodder tho...
