Well, that really depends on the case and jurisdiction, I can't answer that for you. Really, the key part is to force Google to actually provide reasoning for their actions, as they eventually did in the case I edited in links for.
Going to court twice to get Google to pay $0 in damages and not reinstate your account doesn't sound like "the easiest thing" to me. It's at best a Pyrrhic victory.
I get the desire to impose costs on Google for their bad actions, but this doesn't seem like a very productive plan.
Well yes, giving up is almost always the easiest option in any situation. I mean easier than attempting to navigate Google support channels or having the right internal connections.
Google presumably hasn't signed a long-term contract with you to provide any services or continue a business relationship.
Is "We don't want to do business with you any more because our algorithm isn't smart enough to differentiate what you're doing for fraud" actionable?
