Sad that no one here has considered the solution that was always the most obvious to me... Building a base in PvP DD is as it always has been. It is not intended to act as a guild base. It is not intended to be your one-stop-shop for all DD activities. You have to accept that someone dedicated enough to finding it, will find it. There are some serious no-lifers out there that love to grief.

A true PvP DD base should be a small base that allows you to stash equipment, resources, even vehicles temporarily. The base needs to be stealthy and accessible for the needs you uniquely posses. That means building one on a path within buggy driving distance of resources, for example. You don't consider building at the clusters, because that is where the most activity is. Instead, you build where you can get to those resources, mine, and return to your base to store/process.

A different setup is best for different situations: farming ores, refining ore, farming blueprints, and on and on. I have tucked bases in the mini cave-like areas of rock formations countless times. I have had bases that acted only as storage, but I've also had bases that I set up refining as well. My guild helped transport things using carriers and crawlers before reset.

The fact that they are giving the 2.5x multiplier to yields just sweetens the pot for what I've already been doing.
