Moderation

Moderation is moderation;
moderation is not an unavoidable slippery slope to the opposite extreme.

Outlawing

Don't outlaw things that you personally don't want to do.
Outlaw things that you don't want done to you.

Judging A Group

Don't prejudge individuals by their group.  Left-handed people may be more dumb & evil on average, but it is inaccurate to assume a lefty is dumb & evil.  Judge people  based on the qualities that matter -- not groups that tend to have those qualities.

Vices

Drugs best be legal, and strongly regulated.
Regulations/laws best be strong & simple -- no more than 3 pages per law.
To preserve liberty, it is better to tax unprofitable behavior, than to ban it.
Outlaw irrepairably damaging acts.  Dont outlaw acts that might lead to a crime, nor outlaw acts that sometimes result from a crime; outlaw the crime alone, to preserve liberty.  But regulate the causes of crime, to reduce the chance that they will lead to crime.

Fair Trade

The best way to give people a good quality of life, is to live by the rule of fair trade:  trades must be made with the consent of all materially affected people.  (Opportunity costs are not a material effect?)

Unguided Eugenics

To increase society's intelligence without sacrificing diversity, enforce 2-child policy -- dumb people are less likely to live long enough to reproduce.  Also halts overpopulation damage to environment & quality of life.

Pay Per Use

Pay-per-use is better, to prevent externalities.
"Externality" = making someone else pay your bill.
Gas tax and toll roads are just paying your own bill for damage done by their usage.

Unproductive Citizens

Successful/dominant civilizations are probably dragged down by the survival of their weak/lazy members.

What Is Fair Trade

"Fair trade" = informed consent of all people who bear material costs/benefits now/later (5 generations).  Emotions are not costs.  Lost opportunities may be costs.  Risks are costs.
