The problem with Facebook is that it's not exclusive - there are tons of alternatives.
Some even have better features (think Twitter or TikTok or Discord).
Nothing is stopping people from launching Facebook2, Facebook3, etc and having the same technology available - yet Facebook is the major player skyrocketing.
This is an example of the market being irrational longer than expected, in my book.
The value of bitcoin is not in the code, it's in the network. Arguing that the code that runs the network can just be copied is not a very compelling argument.
