If one has a special reason to have inflation adjusted bonds, one should take inflation adjusted bonds, they exist in the Euro area as well.
If there is no special reason for inflation adjustment, one can as well buy US Muni bonds, they are as well very safe and have a higher return. There is no guarantee that there will be a high inflation in the future, although it can happen. Some serious economists think deflation could be as well a problem.
The diary is actually incorrect when it states, that the ECB has flooded the marked with extral liquidity. At the same time when lending out worth about half a trillion dollars, it was borrowing back from the market a very similar sum. The ECB did not introduce new liquidity. The Fed didn't as well. The reason was that the interbank lending rates were much above what they were targeted by the ECB. So in the (correct) assumption, that none of the banks to which it was lending will go bankrupt during the time it lends, the ECB only revived the interbank lending, which stopped, because the banks lost confidence into each other.
