Agreed. I doubt many people are discouraged to travel here because of the fee itself. It's the hassle of applying for a visa, preparing the paper work and spending an afternoon applying for a visa at an embassy, and another trip to pick it up. Sure, if you live right next to the embassy no problem, but most people don't.
For example, my parents are retired, and would like to spend 45-60 days here in early 2023, but they will not bother getting a TR or going for an extension at immigration, so they plan to keep it under 30 days.
To boost arrivals and spending they should make the visa exempt stamp 90 days.
