Is an interesting point of view, but I'm afraid that is missing a few key points
To start I would not define Ucraine's agriculture in the last century as "highly primitive". They were using the same techniques as the rest, but in some of the best black soils of the planet, and with very competitive results that speak by themselves
There is a difference also between
You had a bad crop culturing your land this year, though luck, "unfortunate natural disaster".
versus:
"You don't have any land to culture, because is grabbed now from the Stalin's government" and...
"all the crops from this place big or small are sent now to other places" and...
"An illuminati has been promoted by Stalin [1] to manage this lands"
[1] Lets don't blame the snake oil seller for it, It was directly promoted and supported by Stalin to do the dirt work of systematically pursuing, deporting and killing the real scientists.
And..."He deployed soldiers to block the people to exit their homes and migrate to other areas to save themselves" and...
"While "stubbornly refusing any external offer of humanitary aid that were repeatedly offered", and...
"Even when the first millions of people started to die, Stalin didn't moved a finger to revert the situation or to feed the population"
He purposely let millions of people at their own luck, starving to death confined inside their homes or being forced to eat human corpses to survive.
A few thousands can be killed by wrong choices or bad luck; killing 4-5 millions requires a lot of sustained effort.
Is hard to believe that this was not entirely Stalin's fault or Stalin's carefully deployed plan.
