Lived in the USSR; it is best explored through small business and personal ownership instead of large words and manifestos. The thing is, work is hard. People need an incentive to put in the hours.

If the state requisitions everything above a certain threshold to prevent wealth disparities, as the communists did in the USSR with grain beyond what farmers needed for sustenance, people will not work beyond the threshold out of the goodness of their hearts. Why work extra hours on the fields if you get nothing out of it? Instead, production will drop to exactly meet that threshold. This is how famines were created.

To maintain production while still requisitioning, you will have to force people to work for free.

  > USSR before the destruction of socialism - typically have 80%+ rates of home ownership

Actually, less than 10%. Homes were owned by a government housing department. When you finished school, you were assigned a workplace and given an apartment. Often it was just a room in a shared apartment (kommunalka). You could live there as long as you kept the job. If you were transferred elsewhere, you had to pack your things and move. The quality of housing was comparable to the homes of methheads in West Virginia. The temporary and impersonal nature of the arrangement bred crime and other social problems. In short, the USSR was one huge "company town" that you could never leave.
