let's reframe your statements:
> 1. Hold on to money because it would increase in value over time
"disincentivize poor people from saving"
> 2. Not make purchases because the object being purchased will require fewer units of money over time.
"push poor people into consuming"
> 3. Not invest in starting new businesses because the investor would be losing out on the guaranteed income from holding onto the money along with the fact that whatever the business sells will be worth fewer units of money over time
"Benefit rich people who seek to invest in venture capital"
> 4. Disincentivize individuals to take out loans to start businesses because the value of the loan will increase in price over time.
"make it easier for people to sell themselves into debt slavery"
> 1. The burden of debt decreases over time
"make it cheaper for leveraged investments, de facto restricted to a small class of investors, to exist"
> 2. People are incentivized to invest their money into business
"push middle class people into subsidizing risky behavior by capitalists"
The reason why I am reframing your statements in this way is because a general policy of inflation affects everyone, and by and large the rich (good for them!) already have ways to escape, if not profit from, the generalized effects. The rest of us do not.
There are additional problems to the "perpetual growth mentality", that I don't want to bring up too heavily, like incentivising continued erosion of the environment, natural resource depletion and less conservation.
> You seem to believe that secondary markets (namely wall street) are bad things.
No. Secondary markets are great. What is not great is forcing people to participate, as in, socializing risk while while allowing the rich and politically connected to enjoy the fruits of the casino capitalism with golden parachutes and fail-upwards scenarios. The traditional left/liberal argument is that we need to add regulation to fix that and protect the investment of general public, which, being anti-state-socialist, I am vehemently against (besides which the long history of added regulations seems to only have the effect of ensnaring more of the middle class into the system of socializing risk and paying off the privileged). The only solution is to not have these insidious little pushes that force the general public into these dangerous activities.
Inflation is like proto-matter from star trek II. You think you know what you're doing, harnessing this praeternatural force that can bend and shape society to what you think are "good things", but the cost is you're really making things unstable because of the fallacy of the unseen.
