A lot of traditional economists do agree with you.

It wouldn't work well if you map the existing monetary system onto a deflationary one. The existing system is based on debt creation to keep going, which needs collateral prices that support the debt to increase. If you just dropped this system onto Bitcoin, collateral prices would collapse everything would blow up.

It's difficult to imagine a different system from within the current one. Jeff Booth has a really good book on this, The Price of Tomorrow. A very slow transition from one system to the other would be best for everyone.
