I really don't get it.
If people don't have money to pay a loan how would they have crypto to pay it?
It's the same as saying you don't have 100$ but you have 100 euros.
In February I paid a monthly rate with some funds from my exchange as I was caught off-guard by the lovely spending habits of my wife, but cryptos are basically money, you have BTC you have usd or pounds or dollars too. I doubt somebody would be that keen on holding that it would ignore bills and warnings from the bank while he has the option to sell a few BTC and pay the bill. What difference does it make it's in usd or BTC as long you pay the same amount?
