Kinda, yes. Any problem is a decision theory problem - in a sense. However, we can get a long way without the wirehead problem, utility counterfeiting, and machines mining their own brains causing problems.

From the perspective of ordinary development these don't look like urgent issues - we can work on them once we have smarter minds. We need not fear not solving them too much - since if we can't solve these problems our machines won't work and nobody will buy them. It would take security considerations to prioritise these problems at this stage.
