This is bad.
> Yet it results in more spending but on what?
Well near target inflation rates (which is a positive non-zero number) it results in a mix between consumption and investment.
This is good.
High consumption has been improving the economy, and destroying the earth. I'm not saying I have the answers, but it's not so simple.
It is very good that the default thing to do with excess money is invest it.
This isn't about a decision to buy bread and milk for your breakfast. It's about the decision on whether you invest in a grocery store vs let your money sit in a bank. If doing nothing is more profitable than doing something then society as a whole will gravitate towards generating no economic activity. This has disastrous consequences because the majority of people in a society do not have the luxury of having investments to live off their dividends.
You're operating off a false premise. Do you think all economic activity would be less profitable than the interest rate offered by deflation?
The whole point of investing in any business is to make a return. Giving businesses competition in the form of deflationary currencies will not eradicate businesses from being formed, and there's no evidence to suggest these businesses will be less profitable than holding a deflationary currency.
We see this in various cryptocurrencies claiming to be deflationary with the concept of 'yield', which shows investing to be a function of their wealth, interest, and expectation of return. Inflation does not need to be in the equation for this type of development.
