Whereas , in the sphere of social security , the application of national legislations only would not afford sufficient protection to self-employed persons moving within the Community ; whereas , in order to make the freedom of establishment and the freedom to provide services fully effective , the social security schemes for self-employed persons should be coordinated.
The above sentence is very complicated. Please provide me a simplified synonymous version consisting of multiple sentences:
The application of national law alone does not provide sufficient protection in the field of social security for the self-employed who move within the Community . In order for the freedom of establishment and the freedom to provide services to develop fully , the social security systems of the self-employed must be coordinated .
