Rather mindless post.
There are many expats living in Thailand with age/health/mobility issues.
Some live very far from immigration.
CW for example is a massive building and even from carport to immigration desks is a serious task for some.
With online reporting hit and miss and currently seems more miss, it's not a simple as you suggest.
Your follow up post stating ....
"Anyone can take your form in, even a taxi driver."
That's a joke right..
Try that at eg CW.
