It is true that in a traditional marriage, the husband has the authority to make the final decision on anything pertaining to the home or marriage. But it is a stormy and shallow traditional marriage in which the husband disregards his wife's opinion. As a leader, he has the responsibility to serve those he leads. By listening to his wife's ideas, he learns how to serve her better. Better still, by actively encouraging his wife to explore or develop new ideas and then share them, he is helping his wife to grow creatively. By letting her make decisions, he comes to understand his wife better. A wise husband will quickly realize that his wife is an asset to his leadership, as she provides a perspective on the home and marriage that is never identical to his own. Merging his and her perspectives will broaden the scope for marriage grow, and this includes making it easier to find solutions to common marriage conflicts.
Is the husband obligated to adopt any ideas his wife shares with him? No, he still retains the authority to rule in favor of a different approach, but when he does so, he can be confident that he has explored not only his own ideas, but his wife's as well. He won't be acting from a position of ignorance or blinded by arrogance - he will be making that final decision for the benefit of his wife and his marriage. Encouraging his wife to think independently does not minimize his authority - it enhances it.
But won't a wife who is allowed to have her own ideas struggle to submit to her husband? After all, her submission requires her to align her will with that of her leader and husband. If she is allowed too much "free will" won't she become defiant and want to dominate her husband? A weak leader is controlling, demanding submission through fear and manipulation. Good leaders don't control. Instead of putting his wife into a limiting box from which she desires to break free, the strong leader creates boundaries within which his wife will thrive. A wife that is encouraged to become all she can be, a woman who is free to grow to her full potential, won't be driven to instinctively rebel against unseen oppression. No, this doesn't mean she will never digress from the path of submission. She will simply not feel shackled to the path, and will walk it willingly (even if she stumbles from time to time).
Is it reasonable to think that if you submit to your husband's leadership, you will lose your right to think for yourself? Certainly not. Your husband's leadership is strengthened when you contribute your thoughts and ideas in a respectful way.
