This kind of disproportionality between populous and less populous geographical areas is very common globally in most democratic systems. Obvious examples being the US electoral college - compare a county map and the popular vote totals for Trump v Hillary - and, er, well, our good old British parliamentary system untouched by evil old biased Johnny Foreigner.
Voters in rural Scotland, redneck Hicksville or Malta have disproportionate power vs those in LA or London. It's a fact of life and in many ways perfectly sensible and more democratic than everything being mathematically equal.
