No, let's not lock out content for obnoxious amounts of time. You know what that does? It doesn't make players better, it doesn't make the elite better, it doesn't help anyone. What it does do is create an environment where players harbor extreme animosity towards others for making even the slightest mistake, where people will refuse to play with anyone outside of their linkshell, where people will not even take any risks in trying out new strategies because it could mean a wipe which locks them out for too long.

Time sinks =/= difficulty.
