Strawman. Doesn't have to be nationwide or rival the Supercharger network to be useful. The supercharger network is fantastic, but still far from perfect. For example, there's obvious areas for improvement in density, but near impossible for others to justify investment because they would always serve as a second source.
The big picture is that I'm not assigning blame at all. I can see how the existing model currently makes sense. I can also see that it won't make sense indefinitely. I estimate that 80-90% of the supercharger network's cost to date has been in infrastructure - with the balance in electricity and ongoing maintenance. Furthermore, as it turns out, total cost to date per vehicle delivered rings in right around $2000. When they started the network, they had a clear path to ~$20k gross margins per car. So it made sense to charge for infrastructure and sweep the cost of use under the table.
Moving forward, as the population of vehicles ages and network coverage completes, costs will shift towards electricity and ongoing maintenance. Furthermore, margins will be lower as the product mix shifts towards mass market. There will be pressure to change the model.
Back in the early days, there was a chicken and the egg problem with respect to charging stations - especially for long distance travel. I applaud Tesla for solving this problem and support them in their efforts (e.g. by buying a vehicle and not using the network!!!). Unfortunately, while they've solving the chicken+egg problem for themselves, they haven't done it for anyone else. I think the supercharger network is a huge overall positive thing - I want to be clear that I'm not assigning blame.
But I'm also not going to bury my head in the sand and ignore how it could be better.
Pay per use would be better.
