I don’t think you understand the Australian Senate voting system or Tasmanian lower house or the MMP of Scotland, UK, DE.

They all have ranked choice but are tweaked to be proportional too.

MMP makes it proportional by also giving you a party vote which determines what proportion of seats that party should hold so that you don’t get a situation like you described in Australia’s last election. Better to watch a 2 minute video on it.

MMP is the most accurate/fair proportional system but more complex.

That’s massively skewed. Even though the difference is tiny, Labour got almost a 2/3 supermajority.

One way to remedy this would be to retain ranked choice but make the electorates/districts three times as large and elect three members in each. Just like how Tasmania does but with 5 members and 5 huge districts.

The Australian Senate voting does roughly what both houses of the Tasmanian state voting do and what you are calling for.

The Senate still has ranked choice but also proportional representation because of the multiple members in each district (in the Australian Senate the “district” is the entire state, with 6 members elected each time).

Federal Labor currently cannot pass any laws without Greens support in the senate (unless the conservatives support the bill).

Districts are fair because the member can be accessed by local constituents (in theory anyhow). US Gerrymandering is unfair. Australian Gerrymandering is nowhere near as bad.

These coalitions still happen with ranked choice but only if a minor party is popular in a district.

Except for Tasmania in Australia where minor parties have an even better chance. It has only 5 districts for state elections and each district has 5 seats. Greens often get a seat because their candidate is 5th most popular in a district.

In other states they are now winning seats but fewer than Tasmania.

Ranked choice allows for coalitions like in AU.

Maybe you mean Multi Member Proportional voting like NZ and DE. That is the best system but complicated. US cannot even deal with converting to metric so MMP would result in exploding heads.

It would not have been a problem if you had ranked choice voting.

If Musk sets up his own party that would split the conservative vote so the Republicans would finally be open to ranked choice. Would probably require ⅔ majority in Congress.

But Dems might be too hungry for temporary power to support such a much needed fix.
