Socialism is more effective at poverty reduction and ensuring the meeting of basic needs than capitalism

Coops are indeed a way for the workers to own the MOP in a local way under capitalism. However, the "dearth of these arrangements" being necessarily due to the "non-worker challenges of running a business" is an assertion - there could be other reasons.

These questions and issues apply equally to capitalist democratic governments, so this does not actually address the question of socialism's efficacy in fighting poverty or avoiding wage slavery (vs capitalism).

Your rebuttal is correct in that this is a potential state of affairs under a Soviet-style Marxist-Leninist government. However, under a democratic socialist government, the state would not act this way because the people would not willfully put themselves in poverty.

When the workers own the means of production, they can ensure that they are not marginalized and forced into wage slavery.

Scientific hypotheses can not be proven

A hypothesis being "proven true" is not the goal of the scientific method; the scientific method helps us to find out whether or not a hypothesis approximates the truth closely enough for us to make decisions based on it. To quote George Box: "All models are wrong, but some models are useful."

A new political ruling system in which the president is replaced weekly through lottery should be implemented

President is a job in which one requires experience to be effective; a week is not long enough to build up that experience.

Sharia law should be banned from democratic countries

A democratic society (especially one with a significant Muslim population) may decide to enact some or all of the ideas in Sharia law by democratic means. As long as the will to enact such a law comes from the people, doing so does not contradict democratic ideals.

Governments should only regulate the economy, not participate in it

Government-owned entities can take advantage of economies of scale in industries where infrastructure costs are high.
