Yeah, "bonds" is a fuzzy concept. We also have "intermolecular bonds", but they are even farther from a well-defined structure and require analysis in terms of a distribution of relative configurations.

But I suppose these terms arose historically and are based on some phenomenology of human experiences. Say stuff that sticks together at room temperatures might be understood as "bonded together". So then only gases are understood as lacking bonds. With our molecular level understanding nowadays, that puts very different things in the same conceptual bucket. But history is hard to rewrite...
