Ehh, I'm definitely against people taking away acts of will, just because that individual could act badly on his own behalf. I don't find anything immoral with an action unless it causes the infringement of someone's rights, and if you are the victim of yourself, then to arrest you would be to blame the victim. Makes no sense. However, I'm kind of unsure of myself regarding the economy. I agree with Ayn Rand when she says, "Where a gun begins, morality ends," but then I think it comes down to utilitarian ethics vs deontological ethics (Sorry, philosophy nerd here). While it is immoral to take someone's money by force, I also wonder if it is a huge benefit to society to have a safety net there to catch those that fail or just fall via horrendous luck. Of course, a voluntary safety net would be ideal, but impractical. So, again, I haven't made up my mind. Is it realistic to run a country without any form of safety net? Maybe it is. However, I do think pollution should be prevented by government at least to some extent, because that does infringe on the rights of others. I'm not a hippy about it, but I do think it needs some consideration.
You leave this wide open. Fascism is a government where the interests of business are subjugated to the interests of government. In this case pollution controls. You are advocating fascism. The libertarian would at most use the government to spread the message and set a standard. The people who would be informed would take their own action to punish businesses who pollute. People would also decide if a realistic standard were being set because global warming is not real but the government has siphoned billions out of the economy to pay for new government programs to solve a problem that doesn't exist. Be very careful, the Nazis were able to convince the average German to vote for Hitler's party in order to save the country. The country, if I might add, was bombed into the stone age for supporting Hitler. Don't buy into fascism for the good of the country (or children or the environment).
