What makes satellite have an inherent limited capacity? Like there's no real physics limits on how big you can make a satellite. More reception power = more signal in the same frequency range.

There absolutely are. Launch weight, heat dissipation, energy storage and output are a few of the engineering boundaries that must be respected. You can't bigger one without impacting all the others.
It also has to fit in the launch vehicle with whoever is sharing a ride with it.
Our theoretically ginormous satellite might not much improve capacity (in the cell it's servicing) due to limitation in the assigned spectrum. You can only divide up time and frequencies so far.
Whatever you're doing here, you will need to duplicate that to cover the nearby cells. Then multiply that by a region and that by a country and that by a planet. It takes a lot of satellites to cover a lot of area from a low-ish altitude.
