That said, I don't see you the distinction between controlling the means of production use for one's labor and owning it, when controlling the means of production also includes allocation of the additional value created using them.
It also is also worth noting how far from Marxist theories current thoughts on socialism and communism have come.
Conditional control while you are a laborer whose labor is applied to particular capital (which, to be fair, is one of many patterns advocated within Marxist-influenced socialism, not the only operationalization of the concept) is distinct from ownership which persists until the owner chooses to alienate the property.
> It also is also worth noting how far current thoughts on socialism and communism have come from Marxist theories. contemporary sentiment seem to advocate that individuals (working or not) are entitled share of the labor value created by others, even if they are in another workplace.
Yeah, its not like Marx said anything like: “In a higher phase of communist society, after the enslaving subordination of the individual to the division of labor, and therewith also the antithesis between mental and physical labor, has vanished; after labor has become not only a means of life but life's prime want; after the productive forces have also increased with the all-around development of the individual, and all the springs of co-operative wealth flow more abundantly—only then can the narrow horizon of bourgeois right be crossed in its entirety and society inscribe on its banners: From each according to his ability, to each according to his needs!” [0]

In the same sense that the US electoral system doesn’t preclude more than two viable parties. The system of property rights that defines capitalism doesn’t specify any limit, but the structure it creates promotes it in function.
> The conceptual systems introduced by Marx and others is that only workers can own capital
No, the conceptual system introduced by Marx rejects the concept of ownership as applied to capital [0], though it favors workers exercising control of the capital to which their labor is applied. Different variants derived from this and related ideas have different specific mechanism for this exercise of control.
[0] When Marxists talk about rejecting/abolishing “private property”, it refers to this, because in the Marxists terminology “private property” refers not to property of non-state individuals and entities in general as it does in current common use, but specifically to property rights in the means of production, i.e., capital.
