There is a bigger picture here as well, with some people holding hundreds or thousands of BTC and the price continuing to go up - how might the court system view Bitcoin in the context of divorce and separation?
In legal perspective, Bitcoin can be considered as an asset therefore when there will be divorce the same can be taken into half for distribution to both parties. Now, in the case of the story above, as long as both are still in marriage, I don't think it will be appropriate to pressure anyone to do something against his wish. The wife should not be interfering with the investment decisions of her husband as this can be a cause for differences.
