I doubt the limitation is lost on Wyden et al, but there is a political barrier to getting a bill like this passed at all. It's a lot more symbolic to introduce a bill with no chance in hell of passing the Senate than to introduce one that has at least a fighting shot. That is the piecemeal and practical nature of the legislative process. It will be more achievable to get Senate votes to constrain the government's actions than to regulate business. Until there's a stronger shift in the political winds in favor of more robust regulation of the private sector data collection business, the probability of getting over the filibuster hurdle to pass a stronger bill is remote.
