Your system might be more fair, but not one would use it. Traders want an exchange where they can buy/sell as soon as they receive new information, not in the future when everyone else has same information.

Settlement on share trades is not real time, and no one cares from a liquidity perspective. Settlement risk is a different question.

Who is convinced that these traders actually need to exist?

The share market's function in the broader world is to link long term investors with those who need long term capital for investment in the productive economy. Trading beyond monthly seems superfluous to me.

Today's markets don't operate 24/7 (they close at night for instance), and yet everyone uses them because they have no choice. Limiting HFT can happen through regulation.

Doesn't after hours trading still occur, especially if some significant news is revealed?
