I think your post hides a few ideological conveniences which you've used to bolster your argument, or at least make it suond convincing. For instance,
>total lack of change at a meta-scale like a society only exists in totalitarian societies
Does it? Why?
>in the scenario of a command economy, some of the people involved in the economy would fundamentally need to be oppressed
Why? Where does the oppression come in? If it is being told what to produce then doesn't capitalism do the same, though through a distributed model of command? Isn't it true that under capitalism, one must work by someone else's instructions, by the duration dictated by this other, in the method prescribed by this other, in exchange for compensation often only negotiated by a group of these 'others' (save the power of unions intervening)?
>regardless of any moral or ethical judgements, a totally static economy would be inhibiting of the liberty of any given individual participating in it
According to what definition of liberty? Here's what Marx talked about[0]: communism comes in the form of a stateless society, its conception of liberty is radically different to the English liberal tradition's, which places liberty negatively defined as freedom from interference from others. So it seems like you need to preface "liberty" with "bourgeois liberty", or if you prefer, "classical libertarian definitions of liberty". You cannot take them for given.
>laws and regulations, when done correctly, can increase the number of practical/feasible options available to a populace, even though they technically restrict some of the options that would cause a society to fall apart
Under this schema, a hypothetical restriction on employing labour could do the same - people have more options on how to spend their time and to what end. But it's worth nothing that Marx (or any traditional socialist) never argued for imposing laws and regulations, they spoke about changing society, the whole framework of it. Consider that in Hegel, freedom is defined as the negation of necessity.
