You can give just about anything to just about anyone else.
No.
?
Why the question mark? How am I supposed to give "anything" to people in arbitrary places on Earth?
And more on topic, how am I supposed to send small amounts money to people in those places? And to people who don't have, or can't have bank accounts? Or who don't want to have them? Or who don't want to share their personal details? Or whom I don't want to share my personal details with? Never mind businesses who pay obscene amounts in fees to make these transfers. Your idea about free (in every sense of the word) transactions not being a marketable property is extremely misguided, regardless of Bitcoin.
Bitcoin has utility for me, since I transfer money across the globe all the time and many of my acquaintances already use BTC.
So bitcoin has utility for you because you can send them to someone else, and it has utility for them because they can send them to someone else, etc., etc..
Sounds pretty circular to me. It leaves out the original reason for anyone choosing to acquire a bitcoin in the first place.
Describe to me how you call something a currency if it doesn't have this circular property.
Besides, it
is the original reason, because there is nothing else without significant disadvantages to Bitcoin that I can use.
Bitcoin is a decentralized ledger of which people can decrease a number associated with one of their private keys by some amount and increase the number(s) associated with one or more other private keys by a total of no more than the same amount.
This makes it's uselessness for most people even more obvious. Who cares about those numbers in the first place? What meaning do these numbers have to people? Since these numbers are not representing something people already value (hopefully you're wondering why someone would bother to create a ledger for something they didn't value?), they only matter initially if you falsely believe (or more strangely, pretend) they represent money (this would be the sole source of their valuation).
Sorry but your conjecture is not very convincing, if only because it reeks of historicism. Also, it collapses right after people care about those numbers. Bitcoin system itself is the monopoly of coin production. The coin itself is "backed" by its utility.
As I said before, as long as enough people falsely believe bitcoin is money or that it has the potential of becoming a money, it will likely be traded, but only for as long as enough people continue to believe this. That's why bitcoin was ever traded at a price to begin with and why it still has a price. But unless some changes (to be shared at a later date if not discovered by someone else sooner) are made to the system, bitcoin's price will eventually drop to whatever price the few people (those that will just not stop believing that it's a money or has that potential) will pay for it.
This is spot on. So, for instance, if "few" means 10, you won't call it money. 1000? 1000000? Where do you draw the line to define common? Why don't we focus on the parties involved rather than the ratio to total human population?
What changes are you proposing by the way? Why the secrecy?
Namecoin solved its issue with merged mining (hopefully in effect in a few hours).
Yes, many bitcoin miners will likely help prop up or further increase namecoin difficulty (not necessarily namecoin prices) with merged mining, but if bitcoin prices drop far enough that bitcoin mining becomes unprofitable for most miners, both bitcoin and namecoin will end up in the same situation that merged mining is supposed to get namecoin out of. Unfortunately for bitcoin, there is no larger, more popular blockchain network to piggy back onto when bitcoin becomes unprofitable to mine.
Yeah, that's why I said several years of development is still needed.
Having said that, I don't think miners falling off that fast is not a clear and present danger. If it is, we should change re-targeting rules, which is arguably an easy thing to do.
