The problem with treating tulpas exactly as physical people comes into play when you deal with things like merging, dissipation, and honestly just psychology and understanding of your own brain
The thing about the concept is that you're not going to have completely opposite feelings like fear on the tulpa side and malicious intent/disregard for the tulpa in the same head.
Can tulpas have different opinions and views compared to a host? Sure. Can they have different emotions about the same thing? Yep. But they aren't usually going to be complete opposites

And that would be required for "tulpa rape" to be a thing
Still it is still a possibility where the tulpa wouldnt want to

If you allow people to advocate and promote creating tulpas for sex or creating "sex companion tulpas" then people new to the community will see everyone in the community as thirsty fucks
I think tulpa rape is hardly possible too. Tulpa is part of you, in a healthy brain you shouldn't have that such conflict of interests between two identities
