I have proved that deflative currency will incentivise spending and discourage hoarding permanently when a certain amount of saving is done,
Where? If you have, you're the only one.
so this is not the real reason behind the adoption of inflative currency
You understand that fiat != inflationary currency, right? Fiat can also be deflationary, if that's what you want. Most people don't.
The real reason could be:
1. Without a fast circulation of money, the banks would not make enough income in interest
Why?
2. If people don't spend fiat money, then they don't need fiat money, then fiat money will lose its value quickly, the money printing scam will be discovered easily
So don't spend fiat money, don't use fiat money, and your problem's solved. Presto!
