Exchanging Meso for Maple Points

Nexon doesn't lose money either way. The fastest way to get meso is to buy a WG off the MTS and sell it. Otherwise meso making endeavors involve crafting things en masse or boss running and saving meso to buy things to MTS for NX. Meso through the cash trade room doesn't disappear. It's taxed. Meso:NX conversion makes it disappear forever. If both systems accomplish the same goal but direct conversion takes the meso out of the economy, why is cash trade room better?

Cash trade room is better (for nexon) because it doesn't introduce NX into the economy.
With Cash Trade Room, not a single smega is used without someone, somewhere, having given Nexon a US$ for it.
With this MaplePoints-for-meso deal, people can smega without anyone ever having paid for them.
Why would Nexon want that? Just for the meso sink? Plenty of ways to do that without giving people free cash shop items.
