Unfortunately, physics won't allow for that - with optical instruments you need a big aperture (lens) or you need to fly much lower than Starlink, or both. 1 or 2m imagery may definitely be possible, though! Check out BlackSky for reference.
Problem is that most the interesting bits people want more data on are quite dynamic in space and time, not just time. Even when it's not you don't gain linear subsampling improvements and eventually get diminishing returns with such approaches.
