Each US dollar has it's own individual serial number, but the US dollar is recognized as having value because it is legal tender for all goods and services public or private. There is no such legal staple for Bitcoin.
Nor gold, heirlooms, sheep or socks. That's completely irrelevant as to how something gets valued.
You're not even a good troll.
You are taking one sentence that I wrote and analyzing it in isolation from the rest. The rest explains why Bitcoin is different than gold, or heirlooms, or sheep, or socks.
