The Cost of Running a DApp on a EOS Network: EOS Main Net vs. Wax vs. Telos

For 100 transactions/day on the main net, you pay 0.018 € for bandwith and 409 €/day (!) for CPU. Compare this to AWS DynamoDB (for example), where you'd pay less than $0.0002 for the same amount of transactions.
And storage is even worse -- for just 16 megabytes of transactional storage you pay 2700€/day (!!). This comes out to just over 5 million € per GB-month, compare with AWS prices of $0.25 per GB-month.
Why would anyone want to write DApps with prices like these?
The CGIs was not speed daemons, but you could easily sustain 0.5 request/second (~43,000/day). So this is still way way cheaper than DApps.
