There's no free lunch. If you want hot water, you need to "waste" water by running it until it gets hot. If you want instant hot water, you have to have a point of use water heater, or a recirculation system. With the latter, you'll have costs and complexities if you have a pump. Even with a pumpless thermosiphon system (which not everyone seems to understand but trust me it works better than any pump system) you'll have standby losses. Even if your hot water lines are insulated as well as the return line, there STILL will be some kinds of standby losses. Every situation is different and you'd have to have a tremendous amount of accurate data (insulation R values, length of pipe runs, an almost impossible to measure flow rate, etc.) in which to create a framework in which to calculate what these losses will/would be, or how much electricity its going to cost to pump wasted water. It's a fools game and only one some OCD engineer would even try to attempt.
Bottom line is instant hot water is going to cost you something for the convenience. And we all pay for some level of convenience. "Accept it"; either the inconvenience or some trivial added cost for the convenience. Your choice.
And some of this stuff is a bit crazy; at my new home in the Carolinas, there's natural gas here. But, one of the builders in this subdivision is installing electric water heaters--that makes not a whit of sense. None. Here also, the Carolinians have not accepted gas clothes dryers even when gas is available; they'd rather heat the air with a 30A 220V electrical circuit. Also doesn't make a lick of sense. I had to install a gas line for the dryer in a new home in which there is gas here! There seems to be no shortage of the inexplicable; the things that make you shake your head.
