Hmm, okay, so it sounds like you’re arguing that even if we measure the curvature of our observable universe to be negative, it could still be the case that the overall universe is positively curved and therefore finite? But surely your argument should be symmetric, such that you should also believe that if we measure the curvature of our observable universe to be positive, it could still be the case that the overall universe is negatively curved and thus infinite?
My answer to both questions would be yes. In other words, whether the entire universe is finite or infinite is not a meaningful question to ask because we will never be able to gather empirical evidence to study it.
