Actually a lot of people would be concerned about this. If the average user used 100% of that double power then sure they would love it. Most people do not though. The average user barely pushes a low end M1 to it's max limits.
Why bother with this when you can have a more efficient Mac which uses less electricity and still get everything you need done with power to spare.
The prosumers think as you do, but the average user would prefer a lower powerbill and not have an overkill machine they will never fully utilise.
This makes very little sense if at all. First, like others have mentioned already, just because a chip CAN draw higher wattage does not mean it always will. When you are not pushing it, it will happily sip power.
Second, even if you assume a chip that pulls 220W instead of 110W (as an example from the previous post) and assuming you are pushing it 100% all the time for an average of 8 hours a day EVERY day, you end up paying an average of about $3 a month extra (based on average elec costs in the US) compared to the 110W chip. And this is assuming you are pushing the chip to 100% all the time, which will almost never happen.
And furthermore to offset that additional power use, in most cases you get work done faster which means you end up not pushing the chip that hard for as long, reducing power usage.
Regardless though, no one who is buying such expensive macbooks in the first place are going to care about literally 1-2 dollars (if that even) of additional elec bill per month.
