Do you "get" that some people are proponents of EVs, not because they believe EVs will save the world from the evil of CO2, but instead because they see them as an efficient and economical tool for certain transportation jobs?
Oilerlord has a good point that occasional stops at a DCFC can make sense for medium distance trips, especially when the alternative is renting a car or flying.
I understand that DCFC costs more than L2 charging at home, but it doesn't excuse it from being 5x the cost. The OP said the price is $10 per half hour at an EVGo charger, and people here have reported 50 kW charge rate under ideal circumstances. That works out to $0.40/kWh.
As others have mentioned, there are subscription plans offered by EVGo. From the EVgo website, the price is $0.20/min. That works out to $0.23/kWh, ignoring the monthly fee and 1 year contract.
I pay $0.08/kWh, ignoring the ~$350 I spent for the EVSE and NEMA 14-50r.
Besides all this, you miss my real argument, which isn't that DCFC pricing should be comparable to L2 home charging, but that it should be comparable to gasoline. The fact that electricity is more expensive than gasoline is a slap in the face when you consider the other disadvantages of DCFC (takes longer to "fill up", uncertainty of operational status, more frequent need to "refuel", sparse placement of charging stations...).
Sure, it's fun to read how enthusiasts go long distances in an EV, but I would caution the average consumer from feeling like they will be happy downloading apps, meticulously planning recharges, paying charging subscription fees, and praying that chargers are both working and available when they plan to go beyond the single charge range.
For widespread EV adoption to become a reality, consumers need realistic expectations. If their expectations are not met, it will take a long time to win them over to the EV side again.
