There are some Ahkaam in religion that have no justification except "obedience" and this matter is among them.
If one is obedient to God, he/she should say ok my Lord.
Some have tried to raise some justifications that I think none of them are true and we can't accept them as a reason behind this legislation.

The oil prevents water from reaching the hair or the skin
So one should make sure that the water comes into direct contact with their hair or skin.
You can leave a little area of the head without oil in order to do a correct wudhu.

Allah (swt) states in the Holy Quran that He will forgive all the sins:
Surah Zumar(39) verse (59)
قُلْ يَا عِبَادِيَ الَّذِينَ أَسْرَفُوا عَلَىٰ أَنفُسِهِمْ لَا تَقْنَطُوا مِن رَّحْمَةِ اللَّـهِ ۚ إِنَّ اللَّـهَ يَغْفِرُ الذُّنُوبَ جَمِيعًا ۚ إِنَّهُ هُوَ الْغَفُورُ الرَّحِيمُ 
Say [that Allah declares,] ‘O My servants who have committed excesses against their own souls, do not despair of the mercy of Allah. Indeed Allah will forgive all sins. Indeed, He is the All-forgiving, the All-merciful.

But we have to bear in mind that repentance has some conditions:
 
Tawbah is not accepted from one who merely declares, “I repent.” There are a number of conditions that must be fulfilled before the acceptance of Tawbah. These are mentioned below in the following hadith:

• It is narrated that someone said: Astaghfirullah (I seek God's forgiveness) before Imam ‘Ali (a). He said to him. "May your mother mourn for you! Do you know what istighfar is? Verily istighfar is a degree of the 'illiyyun (people of high station) and it is a word that means six things. First is remorse over the past. Second, the resolution not to return to it ever. Third, to return to creatures their (formerly usurped) rights so that you meet God Almighty in a state of purity in which no one has any claim against you. Fourth, that you fulfil every duty that you neglected in order to satisfy your obliga­tion in respect to it. Fifth, that you attend to the flesh of your body that has grown on unlawful nourishment so that it melts away as a result of grief and mourning and your skin adheres to your bones, after which new flesh grows in its place. Sixth, that you make your body taste the pain of obedience in the same way as it earlier tasted the pleasure of sins. When you have done these things then say Astaghfirul­lah! [Nahj al‑Balagha, saying # 417]

This noble tradition mentions two prerequisites for Tawbah (remorse and resolution), two important conditions for its acceptance (returning the rights of creatures and of the Creator), and finally two points for the perfection of repentance.

Sheikh Makarem Shirazi: Due to the many ambiguities that Bitcoin has, it is problematic (meaning according to obligatory precaution one must refrain from these transactions i.e. you can refer to the second most knowledgeable jurist and follow his opinion.)

Sheikh Vahid Khorasani: Buying and selling it is void.

Sheikh Saffi Golpayegani: It's forbidden and it's a type of eating up wrongfully. Allah is the All-Knowing

It is an obligation for a woman to live where her husband has decided unless she has mentioned in the conditions of the marriage contract that the place of residence is up to her.
And a woman can not leave the house without her husband's permission.
So if the husband is ok with all this situation then it's ok for her
