For real. Everytime I get in the shower I end up having to point the showerhead away and cower from the cold water and I could have just turned it on first?

If you have a hot water tank, that hot water is just sitting there getting cold just waiting to be heated up again. A circulating pump puts that hot water to use by circulating it through the pipes, which has a nice side effect in cold climates of preventing the pipes from freezing and bursting. I doubt it wastes much energy as you think.
Hot water tanks do not just “get cold”; they are fantastically well insulated. And a great way to lower peak energy usage by accumulating heating power, making it possible to use a heat pump to heat the water.
Hot water tanks are usually not that well insulated. If you want to save electricity an easy thing to wrap a good later insulation around it.
