I feel its pretty obvious this person's a gate keeper, so we both know what demographic they are.Simply: no. Placing unnecessarily high time and dedication requirements only guarantees a certain demographic, namely the basement-dwelling teens and manchilds with little or no real world responsibilities. This obviously (gamergate, anyone?) is more likely to have a negative impact on the quality of the community.
Unless you're the said demographic and think you're more deserving than the rest, who by the way outnumber you by a hefty margin and are thus more relevant from a business perspective.
Luckily, this not a binary choice. In fact, the holy grail of game mechanics is the "easy to learn, hard to master" kind. Very hard to get right, though.
