>The global economy is a biological system, and money is its nervous system. This is more than a mere analogy.

If you want to make that analogy you will at least have to pick the right one. Money is more like blood. If money doesn't circulate throughout the body evenly it will develop necrosis or even die. If the organism grows bigger it will need more blood.

>"money is the channel through which we communicate with distant strangers, the original social media... distorting media distorts the way society talks to itself."

This is correct but what this means is that not communicating at all, i.e. never spending your money and never sending a price signal is the worst form of distortion because it breeds speculation on the supply side. Since no price signal is sent, nobody knows what to produce, people will have to blindly invest into the future and hope they are lucky. The cunning ones will try to coerce people into sending price signals by creating artificial needs or reducing production until scarcity sets in and people have no other choice other than to send price signals.

>Hence, prices expressed in money and the price of money itself are the lifeblood of the economy (I mean "the nervous system". Both metaphors work!). By "the price of money," I am referring to the interest rate money earned by doing nothing. Or, more accurately, the interest money can earn from being deposited in a bank. Interest rates indicate the supply and demand for money.

That is only true in a loanable funds model, which in theory isn't a bad idea but that isn't the money system we have right now. In a money system where deposits are created through loans the supply of money is in theory infinite, the idea of a price of money being the result of the supply and demand of money becomes illogical. Insteady the optimal rate of interest depends on yields in the real economy.

>In light of the above, it is common to say that intervention from governments and central banks "distort" money and makes it impossible for investors to get accurate information from the economy

Indeed, central banks and governments act in the worst kind of price control imaginable. A lower bound on interest rates combined with a deposit insurance and bailout scheme that effectively guarantees this price control. This effectively means vast amounts of capital are on unemployment support. The zero lower bound has become the minimum wage of capital.

Due to the speculative benefits of liquidity, people aren't going to lend out their money in long term bonds unless the interest rate is sufficiently high. This liquidity preference effectively acts like a constant which is applied on the lowest possible interest rate. 0% (zero lower bound) + 3% (liquidity preference) = 3%, therefore yields on money must always be positive or new money must be created exponentially (inflation) to avoid paying the 3% interest floor.

A minimum floor on the yield on capital means you must grow your economy by 3% just for incomes to not stagnate, for the standard of living to just stay the same! This isn't growth for prosperity's sake, it is growth just to keep food on the table! If you refuse to pay this yield, money will stop circulating, blood will stop flowing, the organism will die. So governments have decided that we won't pay the yield and must create more blood, fully aware that the blood is being lost via a hemorrhage that will grow and eventually burst.

One last word. If the interest rate on money is supposed to mirror the real world, then what does a positive interest rate mean? It means there is a shortage of capital and that the economy must grow. A zero interest rate means that there is no shortage and all capital is being utilized. A negative interest rate means there is more capital is more than enough capital and that we don't have to utilize all of it. In other words, the latter permits there to be slack in the economy, it allows for supply to outstrip demand and any prosperous economy should be able to do that.
