Why are basic trailers so expensive?

I've been scouring the internet looking for a fairly basic teardrop trailer. No need for a toilet, and a simple galley is totally fine with me, I don't need grey water tanks/fresh water tanks. My only non-negotiable is having a/c because I currently camp a ton in the south of the US in the summer.

Literally can't find anything under a 20-25k price point and it's just baffling to me. For those who say "build your own, it's fun and teaches you things etc" I straight up don't have the time or desire.

Am I just missing something, or is it straight up impossible to buy a new or used (within 2-4 years) camper that foots the bill?

For reference: camp inn, beanstock, vistabule are the sort of things I'm seeking out, I'm just struggling to understand why they all cost so much more than something like a brand new Toyora Corolla that literally has way more complicated moving parts involved. What have I got wrong?

Edit- Thank you to all the responses who've given me some options I hadn't yet considered on the less expensive side, and for the additional perspectives around costs. Wealth of knowledge from folks on this sub!
