The relation between Islam and society is actually a lot more complicated than that. Go to Pakistan and ask 10 Imams about honor killings[1]. Eight will hem and haw, one will say that it's against the Koran and needs to be stopped, and one will say it might be against the Koran but it's so important it needs to continue.
I do find the rules Muhammad laid down to have a lot of problems, but they were a big improvement over the existing traditions in the area and would be a big improvement over what people actually do in Afghanistan.

Go to the USA and ask 10 pastors about drone strikes. Eight will hem and haw, one will say that it's against the Bible and needs to be stopped, and one will say it might be against the Bible but it's so important it needs to continue.
"Those who say religion has nothing to do with politics do not know what religion is." Mahatma Gandhi
Oh certainly they would, though I suspect the ratios are different. Mohammad was running a theocracy within his lifetime, so all the compromises and practicalities that were needed to actually govern. There's still a large amount of tradition that has to be applied, but you can talk about the Islamic way to govern much, much more concretely than the Christian way. Which if you believe in moral progress is a bit of a problem with Islam, but not one I'm going to dwell on when talking about societies that would be better off following the Koran more closely.
And incidentally, your point is somewhat opaque but I believe you're taking that Gandhi quote to mean the opposite of what he meant. That is, it isn't that politics does influence religion but that politics ought to be influence by religion.
