There might be examples of such things, but this isn’t one of them. Companies will not build “3x the necessary towers in cities”. Companies do not waste money building things that are unnecessary. On the other hand, companies WILL build infrastructure in rural areas if there’s sufficient demand. But the tradeoff when you live in a rural area is that it takes more cost/effort to get things, all else being equal. At the margin, that means some things won’t be available, or will be available only at a higher cost.

Government does the same thing, except it response to political rather than monetary incentives (although the two may coincide). So it will serve politically powerful constituencies. It’s still chasing ROI but measured in a different currency. Granted: this does mean the government is “better” at doing cost-ineffective things, but the fact that they're cost-ineffective is a signal that they shouldn't be done in the first place.
