Consumers themselves show little respect for their own privacy. Do we need opt out by default? The answer only depends on how paternalistic you views are.

The US literally kills and helps kill people in order to determine who is in power in other countries. Releasing the hacked emails of a corrupt politician is hardly an evil thing to do. And ultimately, ballots are cast by US citizens, not foreign governments.

Google is providing actual competition. Small companies do as well.

But government - having the power to violenty coerce anyone and everyone into compliance - is far less susceptible to greed, right?

The postal service is a monopoly. Companies are not allowed to compete with it in the business of delivering mail. The USPS was long used as a tool of censorship and political patronage. It was long a burden on taxpayers, and today it has to borrow billions just to stay open (yes, even without having to prefund retirement benefits, it would have still lost $10 billion over the last 7 years). Children don't get an education at public schools. They get bullied and treated like prisoners at public school. They have their natural love of learning destroyed, and their self-confidence undermined at public schools. When they get an education, it's in spite of public school, not because of it.

You might also be shocked to learn that there are many places where people have to drive an hour or more to get to an indoor shopping mall!

The roads are dangerous and the government refuses to be held accountable for the tens of thousands of people who die on its roads every year. The police are brutally violent racists. The military slaughters civilians on a massive scale. Yay socialism!

Government? The same institution that is gunning-down unarmed black men in the streets? The same institution that bails-out mega banks when they screw up and lose billions of dollars? The same institution that drops bombs on wedding parties, schools, and hospitals? The same institution that waged war against the people of Iraq in the name of blatant lies? The same institution that spies on every single phone call we make, every single internet message we send, every single website we visit, every single financial transaction we make? The same institution that steals people's homes to give to big companies to demolish and build over? The same institution that keeps native americans living in abject poverty? The same institution that forces immigrants to attempt dangerous border crossings, and subject themselves to employment abuses just so they can make some money to send home to their families? That's who you think is going to protect us?

Such as dropping bombs on women and children, oppressing racial minorities, excluding competition from the market, bailing out losers...

You must live in a world without taxes and monetary inflation.

What's your evidence for this? There is a growing number of private local ISP startups bringing broadband to underserved areas. There's Google, choosing to get into the ISP business, bringing gbps broadband to an increasing number of cities. There are companies that have IPOs that bring in billions in capitalization. Startup costs are not anywhere close to being an insurmountable obstacle.

If it relies on fins, those would need to be mounted on part of the bullet that doesn't spin as a result of the rifling. If the entire bullet doesn't spin, are the fins enough to keep the bullet stabilized?

It will be interesting to see if this system can grow and mature to make a substantial dent in the market shares of FedEx and UPS.

All creative work is in some way derivative of something created by someone else.

So he briefly offered something for sale. And he also bought and sold some things. And that's illegal.

We should get rid of him, his, and she, and just go with he, her, hers.

If freedom doesn't apply in economic matters, then there is no freedom at all. All action is inherently economic in nature.
