As a 24 year old, single,your needs for insurance are minimal.
Why you might consider it are for these reasons. You are young, so it will be cheaper than buying say at 34. Insurance is always on sale.
Two, there is no guarantee that your health will always be good, you may have to pay additional premiums later or even be refused coverage. Ask me, I pay 70% more than others my age for the same coverage.
Three, insurance ownership with equity values can grow tax free as you accumulate the monies. Consider it like a bond portfolio offering guaranteed returns on portions of the growth, and a long term return of 5.5% or slighly more.
Four, stating sooner versus later means more cash buildup. Just like being in a pension will generate more cash for you by age 65, than if you had started at age 34.
Insurance is only one tool in getting a good start. It is not a panacea.
