You haven't read the manifesto
Marx writes in chapter two,'Hard-won, self-acquired, self-earned property! Do you mean the property of petty artisan and of the small peasant, a form of property that preceded the bourgeois form? There is no need to abolish that"
Marx supported personal property Rights.
Personal property and private property are different forms of property.
No one wants to take your toothbrush. Literally no one.
"Yeah I'm not super motivated to research the failed USSR right now."
Because if you did you'd realize all the lies you've been told.
'You could make a case that some of our businesses and industries are at least partially nationalized."
And what does that have to do with socialism?

You don't understand the context of the manifesto.
It isn't the method to achieve communism, it's what the party he wrote the manifesto for should do if they gain power.
Imediate policy isn't the same as end goal.
You should read the whole manifesto and not what biased people have to say about it.
Edit
Read the book.
Stop thinking what other people tell you to think.
