Clearly, an exemption to 5 (1)(e) has to exist somewhere down the line and Touch and goes are most certainly allowed at unlicensed strips/landing sites, since you are landing and taking off ! Practice approaches, flybys etc are forbidden if within 500' of a P,V,V,S and you have no intention of landing...
5 (1)(c) and (a) apply only to aircraft OVER the congested area.
