I can't conceive the land not belonging to someone, no.

This is just basically like saying "I do not know anything about history".

The land used to be called "the commons". It was owned by nobody. It was everyone's land.

It was taken over by a system called Enclosure, in which the common land was stolen from the people and "Enclosed" by a small few people who took over.

I have no idea why he has such a following. Is it because he tore the whole system down? Is it because he wrote some essays? China didn't start developing until years after Mao left office.

The average lifespan in China was 33 when Mao launched the revolution. It rose DURING the revolution, during civil war conditions simulteously alongside a literal fascist exterminationist invasion by the Japanese. The life expectancy during this period rose despite war because the communists were improving the conditions of the people immediately.

The life expectancy upon Mao's death was 64. It rose further after his death.

Life expectancy does not rise when people's lives are getting worse. He certainly made some mistakes, but you are making an utterly fatal mistake here by looking at "x number of people died" in isolation instead of looking at it in comparison to what existed before.

And if none of that is enough for you I leave you with this:

It has been estimated that, by the 19th century, 40–50% of all Chinese women may have had bound feet, rising to almost 100% in upper-class Han Chinese women.

The ending of footbinding alone justifies Mao as a positive thing all by itself. Without ever having to discuss literally anything else. It was a horrific practice. There's plenty more to use as justification, but footbinding by itself is singlehandedly enough to justify it all.
