Security is about tradeoffs, most notably security vs convenience, but also many others.
Anyone who suggests that their personal preferences in tradeoffs are not just universally correct but also the only reasonable position to hold is just silly.
For most people there are, in fact, no legitimate reasons to run "their own" software on "general purpose" (read: household appliance) computing hardware. Almost nobody runs custom software on their washing machine or toaster.
