What argument does Romeo use to persuade the apothecary break law in and Juliet?

In Romeo and Juliet, Romeo does not use any arguments to persuade the apothecary to break the law and sell him the poison. Instead, he resorts to begging and pleas to convince the reluctant apothecary. Here's an excerpt from the scene where Romeo encounters the apothecary:

Apothecary: "Who calls so loud?"

Romeo: "Come hither, man. I see that thou art poor.

Hold, there is forty ducats. Let me have

A dram of poison, such soon-speeding gear

As will disperse itself through all the veins

That the life-weary takers may fall dead,

And that the trunk may be discharged of breath

As violently as hasty powder fired

Doth hurry from the fatal cannon's womb."

Apothecary: "Such mortal drugs I have, but Mantua's law

Is death to any he that utters them."

Romeo: "Art thou so bare and full of wretchedness,

And fear'st to die? Famine is in thy cheeks,

Need and oppression starveth in thine eyes,

Contempt and beggary hangs upon thy back;

The world is not thy friend, nor the world's law:

The world affords no law to make thee rich;

Then be not poor, but break it, and take this."

In these lines, Romeo emphasizes the apothecary's poverty and suggests that he should not fear the consequences of breaking the law considering his difficult circumstances. He highlights that the world does not offer him any opportunities for wealth and encourages him to cast aside his fear and take the money offered in exchange for the poison. However, the apothecary initially resists, reminding him of the strict law in Mantua that punishes anyone who sells poison with death.
