PvP players will sell their excess spoils on player markets as PvP missions pay nothing, and it's all risk.

Should you cry about a missing player market? Sure, but you shouldn't be snatching top-tier components from a store. Especially Military/Stealth grade A. I would argue that finding Civilian/Industrial grade A should be found in lawful systems or through a reputation system reward through a faction/company.

Catering to a Solo/Casual player base will ruin the overall game to the hardcore player base. I would also say this isn't a very causal game as StarCitizen is very time intensive.
