Because most people simply can't afford, or can't justify the expense of, spending money on something that will be used rarely.
I wish I had a guest room with a comfy bed, but getting the larger house (we don't have an extra bedroom because that is the call we made when buying) and then furnishing it well is simply not something I can justify when it would be used maybe 3 - 10 nights a year.
If I visited Donald Trump and he had uncomfortable guest beds I would suspect an ulterior motive, but anyone else I'd just assume it didn't make financial sense to furnish a spare room luxuriously.
OP, if it's just you, you can probably find a Twin airmattress and pump that would easily fit in your luggage for around $20 at Target.
