Who is scamming who? The government is scamming citizens, is that what you meant? The government will try its best to protect its local currency, but probably it might be done incorrectly. If encouraging citizen to convert foreign currencies to Lira, that is manipulation and the outcome may later not be good.
YES! They are taking something of value from their citizens, and giving them worthless pieces of paper which continue to be more worthless as inflation goes higher and higher.
Not only Lira, it is fiat generally, not that fiat can not be trusted, it can be trusted for spending purposes but not for savings. There was high inflation rate in Turkey and their fiat was greatly devalued, but Turkey is not the only country, even many other countries are like that. But generally, best not to keep fiat, the value of fiat is in what you used it to do, example, using it to buy bitcoin, gold or properties which are appreciative in nature.
We should not also be fooled by banks, encouraging customers to have a fixed account.
