You are talking about comparing a basic web form with an application for unemployment benefits which must go into a federal tax database and be processed using a what I assume is a garbage mainframe system.
It not only needs to be validated, it needs to securely store records, be able to compare them, and hook up to the system that handles payments, etc.
They can't just circumvent it and dump it into some silly Amazon or MySQL database and call it a day. That would require the employees to basically copy and paste that data into the actual warehouse and considering they have 3+ million to go through as it is making it easy for them to process is just as important as allowing people to submit.
For the time being the correct response is a queue gate.
Stop being silly.
