Higher power also means it has to dissipate more heat, so it has to be heavier. And we're not talking about a couple of grams to have an ethernet port or an M.2 connector instead of soldered storage. You need a bigger heatsink, which is made of metal and dissipates heat in proportion to how much mass it has. They typically also have bigger, heavier batteries and power bricks. And you then have to dissipate the heat from discharging the battery at a faster rate.
They also have to dissipate the heat into something, which is often the chassis, and therefore your lap. Not fun in the summertime.
The higher power chips are only significantly faster on threaded workloads, so if most of your applications are poorly threaded it's a trade off in exchange for almost nothing.
