You realize that when you get rid of desire(craving), you will never feel afraid or unhappy?
In Buddhism you have the lifestyle of a layman and you have the lifestyle of a monk. Lay people are basically expected to keep to the five precepts. They are not expected to give up family life, jobs, worldly education etc. Conflicts arise when you try to mix up the two lifestyles.
The Buddha himself usually did not teach advanced Dhamma to lay people because generally lay people lack the mental maturity and sharpness to grasp it and that would lead to confusion.
For example, an ordinary lay person might think, "I must study, get a job, get married, have high ambitions because that is what people do in society or that is what other people expect from me". If you tell to such a person that craving leads to suffering, most likely he would get confused.
But a person with a sharper mind might think "what's the end purpose of all these things people do? Is it to gain happiness? Is that happiness sustainable? Why am I looking for happiness in the first place? Is it because I'm unsatisfied? Is there a cause to that dissatisfaction? Is there a state devoid of that dissatisfaction? What is the way to reach it?".
If you tell to such a person that craving leads to suffering, he would have a higher potential to grasp it and he would be able to mitigate the suffering even if he chooses to live as a layman.
The beings who have eliminated craving completely don't just sit around doing nothing all day. They do chores required to maintain the body like eating, washing etc. They also preach the Dhamma to people. They are never afraid, never worried, never bored, never dissatisfied.
