Why not?

The reason these companies deliver to an address is because historically, that is the most convenient way for them to get your package to you.

Now it would be more convenient for you (and less so for them, given the amount of effort that goes into route planning) to deliver to wherever you are.

A truck would hardly 'chase you around', but might follow you until you've parked, and give the package to you then.

I'd say the service places an unreasonable expectation on the shipping company, rather than on the consumer.
