Casting enmity and hatred among people and hindering people from saying the prayers and remembering Almighty Allah (SWT) are good enough reasons for alcohol to be forbidden.
There is no law without reason in Islam although there are so many Islamic laws that we do not know their reason, but some Islamic laws’ reason have been stated in the holy Quran like alcohol. According to the verse 219 of surah al-Baqarah, there are some profits in alcohol for the people, but its sinfulness outweighs its profit. Moreover, if you refer to the verses 90-91 of surah al-Maida, you’ll find more reasons for the prohibition of the alcohol such as casting enmity and hatred among people and preventing people from the remembrance of Allah as well as the prayer.
In addition, nowadays there are lots of non-Muslims who have found out that the alcohol as an intoxicant is harmful for human' body and soul. They are going to reduce alcohol consumption or remove it from their life.
