I think you've missed his point. If the ECB prints more money but most of your trade is with other Euro countries (which it will be) then you can't really use the devaluation trick.
That's what Latvia did - 20% wage cut across the whole country, up to 40% wage cuts in some areas. Government sector lead the way and privates followed. Devaluation also destroys any savings that people might have AND makes the country less safe for the investors.
To implement, yes, but the impact is the same. Those devalued wages are now worth less when it comes to buying imports, and since (to a first approximation) everything in this globalized world of ours is imported, even local goods and services have to hike up prices in response.
