Besides i think all communists forget that self suficiency is posible.

Yes, if subsistence is enough for a person that is an option, but if you want flashylight boxes, tennis shoes, toilet paper, delivery drones, et al, nobody can do that all on their own.

Keep working, while refusing to pay for anything, continues to make and distribute goods, but it does put a dent in the crapitalusts' pyramid model.

They are the only ones that will be mad about that.
The average worker will be better off under this proposal, once they have had the shadows in their minds cleared away by new knowledge.
Leisure time will explode when it isn't all sucked up to the top for the crapitalusts' whores and wives.

Do you want life extension technologies to only go to the folks that have brought us wage slavery, death, and war on an industrial model?

When the doctor provides his services and chemistry for the same reason that the carpenter built his house, for the same reason the sewer workers keep the sewers open, for the same reason that the truckers distribute everything, because this is how we work together to have more, the folks doing the work will know true freedom.

Rather than working them even harder/longer to the benefit of the few, they get the true value of their labor, not just what 'the market' is willing to bear.

The only people against a free distribution model are the ones that benefit most from the current model.
Comfortable slaves never rebel.

Like you make it seem as there are only two options: wage slavery or communism.

If you want consumer goods the work has to managed in some manner.
The larger strategic management system now is wage slavery to the bankster elites that create money from nothing and trade it to us for our lives at the biggest discount they can arrange.

I propose that it is better to make a model that incentivizes self motivation based on reputation and pride.
We get some of that now, but the list of improvident is far longer than that of the provident.

The current model is not sustainable without massive wars destroying all who disobey.

Is that not what is playing out in the world today?
Crapitalism at it's highest practice?
This crapitalism is state of the art, cutting edge technology.
Do you intend to follow it's course to the end?
A true belieber?
Or are you ready to explore the other options on the table when most of these political philosophies reached a broader audience?
They were crowd sourced to a crowd that had a better idea of what freedom is than the current crop of masses, but were restricted to 'elites' after the red scare of the 1920's.

This is where the concept 'communism' was hijacked by the statists.
Any fruit from the poisoned branch is also poisoned.

Rule by force is the disease, who and how are symptoms.
The current 'definition' of 'communism' is controlled by the statist authoritarians that thought killing you made them right.

(which means sell products for less).

It is impossible to both not sell things and to profit from their sale.
All work is done on a cooperative basis.

The shoe maker makes shoes because the tomato grower grows tomatoes because the warehouse puts all the consumers together with a producer.
It operates on the honor system, of all things, eh?
Expecting honor from converted crapitalusts, could be folly.

make your tools from scratch.

I tried that, Kurt Saxon was the master, but even he said that you need to team up with neighbors in mutually supportive endeavors.

I am afraid your 'man vs wild' has been tried and most folks choose division of labor as the most productive method of raising standards of living for all.

I claim no one owns what they did no put in labor to produce.

I am with you there, we just don't want to starve our bums into living under bridges, we give them more dignity than that.
Crapitalusts shoot starving victims of their greed outside warehouses of food the crapitalusts tolerate spoilage losses of,...

Rather than feed people they throw it in the trash and guard the trash against scavengers.

Hardly a model I could continue to support in good conscience.

Especially when fully functioning alternative models have existed since 1887.
