Deflation doesn't discourage investment and consumption. You still need to eat, have shelter, and pursue happiness. It increases the bar at which you will part with your money, as merely holding it has a high level of return. This is a superior system to me.
Euphemistically rephrasing something is not a refutation. Inflation does not make investment decisions "mindless", but deflation does make the average risk adjusted return on an investment negative.

The "high level of return" is at the expense of people who are not freeloading, who are forced to create this return for others by making more stuff for less money. Why is it superior for the monetary system to be designed to reward those who put in no effort and take no risks at the expense of those who do?
You can have an economy with a single dollar, if it can split far enough. Printing new money isn’t increasing the total amount of wealth in the world. It is redistribution.
Or you can just put your money onto a bank account that nets interest. The fact that interest rates are down is actually the sort of result of deflation. The reserve currency status puts immense deflationary pressure onto the USD. The government is forced to go into debt to cancel this pressure. If it did not do so employment would plummet.
There is not deflation happening right now. There is massive and sustained inflation, which you can see all around you in terms of high quality food prices (meat, cheese, seafood), housing, all forms of education not subsidized by the government, medicine, cars, and on and on.
The reserve currency status of the US dollar is a side effect of the US' relatively brief global hegemony which is rapidly collapsing, plus the reduced global importance of oil which has been priced almost exclusively in USD. There will be many threats to USD from other countries (China, the EU) and experimental technologies (Bitcoin, Ethereum).
Several generations of economists have bought full-on to a failed economic system. We have been seeing many problems with it over 40 years since we removed any pretense of the gold standard,[0] but we have seen it over and over and over with various crises. Anyone who thinks our current monetary system is the best humanity can do is not thinking critically.
This is bad for investors and producers spending money now in the hope of earning more money in future.
On the other hand, simply holding onto cash is risk free, and that cash will have increased purchasing power in future (at the expense of the producers forced into offering lower prices to get money circulating again)
An economic system which deters investment, production and consumption but rewards inactivity is not a healthy one.
