How is advocating for the eventual abolition of private property count as being timid towards landowners? It involves sweeping collectivization of land, something easily achievable and already done at scale in most socialist countries.

Regarding increased specialization alongside human knowledge, this is true at the level of the profession, not at the level of the worker. Work is designed to be as readily replacable as possible, wherever possible. An RF engineer working at NASA may have a learning curve, but the underlying basics of how to perform their job can be transfered to similar roles elsewhere. Practice and proficiency is helpful, yes, but we must consider these socially, not individually.

You entirely missed the point on carpentry, smithing, etc. These are almost entirely performed by machines in factories. Artisinal creation is step by step being abolished in favor of automated and machine assisted labor in large factories. So too will this apply to engineering, medicine, etc.

The idea that an advanced communist society would be unable to outcompete a market-based society in standard of living is as laughable as the idea of a feudal society outcompeting a capitalist society. For starters, communism must be a global system. Beyond that, communism rests in highly advanced productive forces too large in scale for markets to function to begin with, so even if we had a hypothetical communism in one country, there would be no need to go to a market-based society just like there’s no need to go to feudal societies for a higher standard of living.

The necessity for these advanced productive forces is exactly why communism does not yet exist, just like nuclear fusion as an energy source at scale does not. It needs to be built up, not simply willed into existence at the stroke of a pen.

You have no clue what you’re suggesting, no matter how many times I state it.
