I'd like to slightly shift the discussion's focus for a bit and talk about the strategies that anti-robowaifu propaganda will use. Apologies if this is kind of a ramble.
The anti-robowaifu political strategy may be more general than just robowaifus. Even if the average robowaifu has the combat capabilities of the average protocol droid (which makes a certain amount of sense because a robowaifu is essentially a protocol droid with a specific focus on sexual protocol), there will doubtlessly be people looking to build combat models. Pointing out how difficult it currently is to build a humanoid fighting robot will fall on deaf ears, because robot haters will be looking to ban humanoid robots in general not on the basis of what they can currently do but on the basis of what they might be able to do in the future.
Let's suppose that my AI video generator setup actually works. If it does, I imagine that by 2050 or so, it will be possible to run high-quality combat algorithms that extend well beyond aikido locally on a humanoid robot, meaning this feature will no longer be high-end but the standard. Research into using these sorts of AI video setups not only for combat but for dynamic robot movement in general will be funded by people who want a more realistic sex experience from their robowaifu. No longer will robots be clunky contraptions that are stopped cold by a flight of stairs. They will be capable of dexterity equaling and surpassing the best human athletes in dexterity-focused sports. I play a lot of RPGs, so when I think about things like this I tend to think about them in terms of RPG stats and character builds. Humanoid robots suitable for mass production will have low Strength and Constitution but extremely high Dexterity. But most importantly they will have high Charisma, this being exactly the goal of this little enterprise. These traits will be seen as a threat by more than just feminists.
I suppose the main point here is, the Robowaifu Legal Defense Fund may end up spending most of its money not to defend robowaifuists in court but simply to keep robowaifus from being outlawed. There are just too many groups that would want this ban to happen. We've heard about the impending robot takeover for decades, but what almost every portrayal of robots fails to understand is that these issues are basically just an extension of current politics.
This brings us back around to robowaifus being accused of spying for enemy nations. But diplomats are in many ways just officially sanctioned spies. Maybe we could get some country to extend diplomatic immunity to robowaifus? But more likely, robowaifuists will have a terrible choice; either be hunted in westoid femishit nations and forced to leave, or somehow get enough corporate backers who understand the potential benefits of advanced robotics to get not only protective laws but an entirely new legal framework enacted that protects robowaifus under "high-tech innovation" initiatives. This is similar to an Asian special economic zone; many argue that western countries already are economic zones more than actual nations because they obviously don't value the lives of their people, so maybe we should make it official and try to create a special zone where we can make that work for us rather than against us.
