Again, this is a classic strawman argument.
I would like a usury free banking system AND ban of alcohol in Pakistan.
Pakistan, at this point in history, has in its power to ban alcohol but can not change its banking system entirely since it's not a financial superpower like U.S. So what does the logic dictate?
Pakistan bans alcohol, and works (along with other Muslim nations) to reach the point where the process of usury free banking system can be started on some major level.
That is common sense logic that follows through.
What is your logic? Well, you don't have one. Yours are mere excuses and complete ignorance of Islamic law (hence you equated music and dance with alcohol, even though they belong in completely different categories under Islamic Shari'ah!)
