This isn't in the right section. It should be in Meta.

But to answer your question, NO. Merit should not be sold or bought.

That means that merit can simply be bought or sold for any arbitrary quality posts. That opens the door for spammers who should be banned getting merit they shouldn't be getting.

Merits are for quality posts and good behavior only. When you allow the exchange of merits for money, you take away that property of merit that the admins wanted in order to keep spam under control.

Buying/Selling merits undermines the very principle that created the merit system. Ergo, no. (BTW WHAT DOES ERGO MEAN?)
