The longest blockchain are accepted as the most authoritative.
Why would the nodes be aware of the longest block chain?
Unless the evil peers are able to generate enough mining power, they can't discard transactions.
Lets, for the sake of the argument, assume they don't. What makes you so sure I can't make others do the work for me?
While evil peers can refuse to transmit or rely transaction, it only took a single peer to connect to the authentic network.
How do you know it's authentic?
Also notes that the bitcoin network do not use any form of identities other than IP addresses themselves. So the attackers would need access to million of IP addresses to create that many evil nodes.
or 0.0000000000000000000000000000001% of the IPv6 pool ;-)
You seem to assume the value of BTC is not going to increase despite them becoming increasingly hard to generate. Are you saying you expect bitcoin to fail?

You would need to control 100% of the network view of the node to fool the node.

You would need to gain access to tons of PCs to take over the network. Not to mention it get harder when the total hashing rate of the network continue to increase. Even then, it will be very noticeable that somebody is attempting to doublespend.
but actually, BitCount identities are public/private key pairs and you can have them in an infinite amount.
That have nothing to do with P2P identities.

The longest blockchain is considered the most authentic.
IP transactions are depreciated and disabled by default. They are also known to be insecure.

I acknowledge that Amazon could be profitable, but they are certainly worser option compared to buying ATI 5790s.

/economics fail
Difficulty to generate bitcoins does not cause them to increase in value. Their increase in value drives up the investment in mining, which then drives up the difficulty.

You seem to not have done the math yet.
