"Taler is for merchants" it seems to be some sort of p2p system.
All crypto "currencies" lack a price stabilization mechanism.
USDT seems stable but you have the counterparty risk. There is a counterparty risk with Taler too similar to the cashu mints people are promoting here but it's simpler and doesn't need a blockchain.
As for the quantitative easing, inflation for USD and other similar currencies is in the low single digit % I can live with that.
