柏拉图让护卫者远离财富以达到对财富的不屑，从而不为财富所困，正如某些家长也让儿童远离电子产品的态度。护卫者是人，儿童也是人，理想是完美的，现实是骨感的，只有少数人能做到。谈“虎”色变，结果“虎”真成了虎。
也许将之平常化，更可能减少对其的渴望。

And they alone of all the citizens may not touch or hand silver or gold, or be under the same roof with them, or wear them, or drink from them.
在所有的民众中，唯独他们不得触碰或或手持、传递金银，不得与金银同处一室，不得佩戴金银饰品，也不得使用金银制饮器。

The Story of Philosophy《哲学的故事》第1章Plato第7节VI. The Political Solution第5段第4句：

So much for incompetence; as for rascality we may provide against that by establishing among the guardians a system of communism:
In the fist place none of them should have any property beyond what is absolutely necessary; neither should they have a private house, with bars and bolts, closed against any one who has a mind to enter; their provisions should be only such as are required by trained warriors, who are men of temperance and courage; their agreement is to receive from the citizens a fixed rate of pay, enough to meet the expenses of the year, and no more; and they will have common meals and live together, like soldiers in a camp. Gold and silver we will tell them that they have from God; the diviner metal is within them, and they have therefore no need of that earthly dross which passes under the name of gold, and ought not to pollute the divine by earthly admixture, for that commoner metal has been the source of many unholy deeds; but their own is undefiled. And they alone of all the citizens may not touch or hand silver or gold, or be under the same roof with them, or wear them, or drink from them. And this will be their salvation, and the salvation of the State. But should they ever acquire homes or lands or moneys of their own, they will become housekeepers and husbandmen instead of guardians; enemies and tyrants instead of allies of the other citizens; hating and being hated, plotting and being plotted against, they will pass through life in much greater terror of internal than of external enemies; and the hour of ruin, both to themselves and to the rest of the State, will be at hand(416-417).
浙江大学译本： 同时民众中唯独他们不能触碰或处置金和银，不能用金银摆设装饰房屋，不能穿金戴银，也不能使用金银器皿。
