2kWHr/day is about 500 watts of solar panels (just for starlink, similar math for the rest of the stuff). So that's about $750 plus brackets, wires and stuff. You'll need a battery bank and you will trade off the size of the battery bank against the size of the solar array to survive partly cloudy days, but there will always a cloudy period longer than your batteries will provide, so get a small generator running on whatever fuel is convenient (you want to charge using at least 1/4 the capacity of your generator to keep the efficiency up, so small generator unless you have vast batteries). Then you don't need such a big battery bank or solar array.

In the cost of a small home, the solar/battery/generator is minor. $1500 panels, $1000 inverter charger, $1000 lead acid batteries (5 years, then lithium will make sense), $2000 generator, $2000 more because I underestimate… $7500 all in.

Fantasy is still a go!
