Over short distances sure, but once you're talking thousands of km a pipeline is way simpler.

That's nice, but it doesn't help the local collection network in the solar field. Using large separate electrolyzers driven by conventional PV lets you avoid that.

Unless the destination of the electricity is also next to the local collection network the pipeline can be simpler. It's certainly not going to be a worse idea.
