This is an incredibly well written response and I apologize in advance if my response comes across as overly cynical or perhaps dismissive.

My main concern with the complete abolition of private property is that unfortunately I don't have enough trust in most governments to fairly distribute resources. Therefore I think a mixed market economy with a strong social welfare system is the most feasible method. Through this, we can gradually work towards socialist principles without completely alienating a large section of the populace. I don't think a direct transition would be sustainable in the long term unfortunately.
