And I probably would too.I think there's every sign that all the other Avengers considered him one.
But legally? Seriosly? You honestly think the MCU America, in the couple of years that Vision existed, would have enacted legal changes to make a sentient AI a full person under the law AND legalized marriage for him and Wanda, a terrorist in hiding at the time?
Good luck with that.
Sure, we, the audience and certainly Wanda, think of Vision as a full person and consider her marriage to be valid. No arguments from me about that. But, when SWORD takes the body and begins to try to reverse engineer it, they are 100% within the law to do so. Most people wouldn't even bat an eye at them doing this.
