Libertarianism is a very wide spectrum and isn't really nailed down to a single ideology. There's forms of socialism, capitalism, and communism with libertarian counterparts.

I don't really say this outloud because people get the wrong idea but I consider myself a libertarian, but I do not associate with any party (especially not the de facto american libertarian party)

My beliefs are this:

• You should be free to do as you wish that does not impede on the freedoms of others. For instance, you should be free to use substances as you wish, but you shouldn't be free to operate a motor vehicle or heavy machinery under the influence because it is dangerous and could injure or kill someone, therefore impeding their freedoms.

• The government should have minimal involvement in regulating the people, and the people themselves play a role in governing the country. Get rid of the electoral college, popular vote should be the way to win elections.

• I have absolutely nothing against taxes, but I think the people should have a choice on where their tax dollars go on an individual level. Everyone gets a budget set accordingly to their income, and the individual chooses (at least a percentage) of where their tax dollars go. Every year when tax time comes, you record this to be audited. This way the government can still allocate funds where needed, but they can't overinflate anything's budget without the approval of the people, or vice versa. BTW, no tax cuts for "charitable donations", if you truly wish to be charitable, then you can donate along with your taxes :).

This is unironically the best approach in my opinion. Not looking to start a debate or anything, just thought I'd give my .02. I know the system may not be perfect, but no system is.
