Yes. I would think it unreasonable. I know a ton of remote people including myself and we all travel quite a bit. Now a job with 25% travel should certainly state that in the job description but if zero travel is non-negotiable you need to specify that up front—and don’t be surprised if you run into issues if managers change.

You are not in a role position if you are required to travel. It isn't as common as you think.

Remote means you are not assigned to an office period. It says nothing about whether you never/rarely travel or travel essentially 100% of the time eg many consultants.

Obviously people should take positions that align with their preferences however. Just be sure to specify upfront and be prepared to move if circumstances change.
