As they are now, yes they are better off closed.
I've had this similar question from many people, including some of my closets friends. And it really is sad to see that Islam has been relegated to just a bunch of rituals and you people just cannot see past those rituals. Without these rituals there is no Islam for you. And that is why you fight tooth and nail over hadith you havent read because then your rituals will go away.
You do your 5 daily yoga sessions, give a buck to the beggar outside the mosque and once a year go around a brick bldg and kiss a stone and consider your Islam completed and done and ticket to jannah booked. Outside of that you can do anything you want. Thats the mentality of the average Muslim today. He's done his duty for that day, thats why take Pakistan as an example, big bearded sufis with that scar on the head, praying 5 times daily in the mosque, bajamat, are the ones who are doing fraud, stealing land, milawat, hoarding, profiteering, lying through their teeth every time their mouths open, stealing property from widows and orphans, but as your ozzy brother ewwww Hoblos said he is still better than who does good deeds all day long but doesn't do your namaz
Islam is not a bunch of rituals, its a way of life, it's main aim is to help humanity in creating a fair and just society so everyone can life a decent life, after having faith in Allah, his book and his messengers your main aim is to help others and build a better society to the best of your capability with whatever Allah has blessed you with.
Your Mushrik Islam is a selfish Islam, how does your namaz help others? How does your hajj or umrah help others? You do all these things to help yourself, to clean your own record of sins.
