You make some great points. I made that "people don't change" mistake that I despise when made by other people. Whadda hypocrite!
I agree that you don't really want to mix in financial incentives too much. That is why I want to just use a transaction tax. Government picking incentives prevents the market from optimizing and has added a huge overhead in IRS agents and accountants, while disincentivizing interpersonal commerce. The loss of economic activity is immeasurable (not without being able to compare parallel realities)
The main thing I wish we could collectively knowledge is that the main function of a society, like every living thing, is to raise the next generation in the values that created it. We seem to think we can have a society that encourages goals other than continuing society and relationships without life.
