You're in builder's club meaning you pay for it every month, therefore it's no longer free.
IIRC it's $5/mo for that, so if you've been signed up for club for more than four months you've already spent more than you would on Blockland.
One of the core principles of mathematics is that if x = y, y = x. Therefore, if x = y, y HAS to = x. Whereas is your equation, x = y, y =/= x.
It's the English language, not mathematics. For someone who believes themselves that smart, you sure do make some elementary mistakes.
