The prophet Muhammad was a polygamist. Should there be laws that forbid Muslims from imitating their Prophet?
If you are a Muslim, you must have no objection to polygamy, right?because it was the practice of the Prophet whom God chose to bring the world the true Faith, it can't be a bad thing, right?
There's many things to develop here.
First the reason why it's allowed, our personal choice as muslims, then the current situation.
1 Actually the muslims were suggested to marry widow women when marriyng multiple women like the prophet did.
Many of the Prophet's wives were widow or he married them for political reasons.

2 It's not an obligation for muslims to marry multiple women, it's not an obligation for women to accept polygamy.
If they disagree and the man still marry an other woman she can divorce.
3 Some muslim countries forbid polygamy : Turkey and Tunisia
In many muslim countries it's not that common, i think it's more the old generation
Muslims living abroad (non muslim countries) in general don't marry more than one woman, except some from the old generation.
I don't know anyone who married multiple wives.
I think it's more for the rich people or from old generation.
