I think the crux is what "having data" means. Think of Van Vreeswijk & Sompolinksy (https://doi.org/10.1126/science.274.5293.1724). Did they "have data"? In the strict sense of analyzing data in their work, certainly not. Did they "do science"? I would say: definitely!
Some might nonetheless say that Van Vreeswijk & Sompolinksy didn't do science. Well, then what about other work that didn't analyze any data, but relied on qualitative observations in other data-driven papers to inform their modelling, or - more loosely - their formulation of new hypotheses? Once data informs their work, does it mean for them to "have data" even if they didn't analyze it themselves?
This quickly leads to the question of what it means to "have data". If we would discard all work that doesn't directly analyze data as not doing "science", almost all of neuroscience theory wouldn't do "science". If we include work that relies on others' data-driven observations, then almost all neuroscience theory is science.
