Because this is what is at issue here. Whether your private property and your inalienable rights to do with your property as you desire can be violated by the whims of government.
By personal assets, if you mean those that are not owned by the company, you never surrendered your right to them. If you use them in corporate business, however, then they can be subject to the laws involving corporations.
If, on the other hand, you mean the personal assets you transferred to the corporation, then the moment you transferred them to the corporation you surrendered your private property rights. In fact, that would be WHY you transferred them to the corporation, SO they would NOT be your personal assets anymore - for tax reasons, liability reasons, whatever. Instead, once you transfer them, the corporation - the legal person - owns them. And you, in turn, own shares in that legal person/corporation. That's how it works, and WHY it works.
So you share the argument of the Obama regime and the MarxoFascists: that all business is public and therefore belongs to the Government and as such, the personal rights of the owners are non-existent.
Which means there is no such thing as private property rights anytime someone engages in public business or public activity if the government so-chooses and decrees.
Which means if you own a business and you refuse to provide services and benefits for those things which violate your conscience, religion and principles, too damn bad - because if you want to conduct business, you have no rights.
That is the entire issue.
