Why is Crafting still in the game?

[L-D-Omlette]

The way I have understood it from what Dev responses/community rep posts is this:

I can spend time running dungeons to get tomes to get my i70 gear, or I can speed that process up by buying i70 crafted pieces from other players. At present since these are the highest crafted pieces that's the best I can do.

With 2.2, i90 crafts will be introduced. This will mean that the fastest way for me to get i90 (assuming I'm not already there from the last 6 months of myth grinding/coil drops) would be to buy it from the community in the form of crafted gear.

This creates a viable system to get to the same baseline.

For the sake of argument, let's say the new max iLvL is 110. Would the community be ok with someone buying all i110 gear from the MB and being at the top gear level without running any content? Would it be more responsible to allow that player to only buy their way into i90 and make them earn the next 20 item levels?

Don't get me wrong, I am all for having crafts contribute to endgame. Personally, I think the best way for this to occur is for dungeons to drop materials (or for tomes to be able to purchase mats) that can't be traded or sold, but can be prompted to have another player craft, just like melding. The crafted gear from said materials can also not be traded or sold. These crafted pieces would be on par with the gear drops from the dungeons, or the tome equivalent.
