Speech is the use of language to communicate ideas and thoughts. A payment is not speech. Paying involves transmitting of a financial asset. It doesn't involve the use of language to communicate ideas and thoughts. Therefore, it's not speech. You can't arbitrarily decide that something is speech, just because it suits your interests. This is not how things work.
I don't need to, mr. creates-strawmen-to-try-to-avoid-the-real-discussion. Many people already hold the view that certain financial activities reduce to the freedom to speak or pursue happiness. It didn't come from me. Good luck convincing anyone that you've ever experienced real threats to your human rights.
