Okay, you pedants, it's not time to argue about tautologies again.
1 BTC = 1 BTC is a true statement.
Connotations derived thereof are used as rhetoric depending on your interpretation.
The only reason anyone says this is to peddle their argument with a meaningless statement: the magic is that it takes the form of whatever argument and remains true, thereby having you falsely believe that you agree with their argument. In reality, you would agree with "circles are round because circles are round" purely due to the fact that it was self-evident. When you don't look at it for what it is - the meta structure of the sentence rather than its words - you can project random beliefs onto them.
