I don't think you understand the goal and should probably just move on.
ArcheAge is a themepark mmo featuring sandbox elements with a strong focus on PvP. If you don't want to PvP you can still play but you'll miss out on a lot of content. They are fairly open about that. I really don't understand how people don't know it going in.
Paying for AH use is a necessity. I played ArcheAge on the RU servers for about 2 months. Before I left the market had been totally destroyed by bots. You can still sell stuff and without losing a % to the AH by selling it the good ol' fashioned way... forums and standing in town yelling "BUY THIS!"
A large amount of the time played was also as a basic account holder. I still had tons of fun. Leveling. Killing people. Carrying Packs on Trade Runs. Then again, I knew what to expect before I started playing. I didn't jump into a game an expect every aspect of the game to be free because that just isn't how it works.
Also, the premium is cheap and amplifies hours of fun. If you don't think you should have to pay for entertainment go watch YouTube with ABP and twiddling your thumbs while waiting for your Guardians of the Galaxy torrent to finish downloading.
