It's impossible to argue "nothing can be argued". In fact, "Nothing" can't be argued, even if we address "Nothing" in the positive sense, ie Nothing as "something". The only way to address "nothing-as-something" is via the semantic trick of citing a "semi model" (of reality). Concisely, any conventional model of "space time" (e.g. motion in expanding space) can be equivalently modeled as a "static" universe (Nothing) with "contracting" content. The "static" semi-model of the universe is the inversion of the "Big Bang" scenario, namely internalized self-processing amounting to "contraction" of objects and time-scales (instead of a big explosion with expanding space). Because it's "static", it can be addressed as a coherent thing, namely a boundless domain. Coherence means "sums to zero value", and hence the coherent semi-model is essentially "nothingness", which owing to boundlessness is synonymous with "pure freedom", or else "infinite mass".
