Controlling the what happens on the client.
You control what happens on the client by requiring of it the least possible functionality ("fill this form in"), and placing no application logic there.

If you do validation on the client, this is only as a convenience to the user, and all data validation is done again on a server - and significantly more rigourously.

Simply put; don't trust the client.

Client-Server has too many problems to be useful in many real-world solutions - but these limitations, and alternative architectures have been well understood for years.

A more interesting question might be "Why to people persist in using client-server architectures?". That remains a mystery to me.

(Incidently, even with Client-Server, you can mitigate a lot of serialization issues with optimistic concurrency control, rather than pessimistic table (or row) locking.)
