No, it will not be a sensible choice. There are some pretty deep, social problems in the crypto space that make this an extremely unlikely outcome.
The fundamental issue is that creating scalable, cheap credit infrastructure for mass economic activity is fundamentally in opposition with creating an investment that will continually gain in value. You see this really clearly in Ethereum, where’s gas fees can be exceptionally high compared to traditional financial institutions.
Ethereum's gas fees have nothing to do with the price of the base asset: it has to do with limited block size availability. When the network is congested, block size is limited and this causes transactions to be bid up in an auction format to get in first.
This is one of the costs of decentralization. However, recent advances in Zero Knowledge Proof cryptography has paved a path for Ethereum to take to get to VISA scale and beyond and be able to process 200K transactions per second (at pennies or less per tx): see https://zksync.io/ and https://starkware.co/.
