Have a look at https://en.wikipedia.org/wiki/Kansai_International_Airport
From the Starship Noise Assessment https://www.faa.gov/sites/faa.gov/files/2022-06/AppendixB_No..., it looks like you need maybe 20 miles distance for a tolerable level of noise (around 100 dB)
So I'm not sure regular launches from the lake will be tolerated by the lake shore's inhabitants. This is why Starship launch platforms should be 30km from shore (not 20km as I wrote previously)

>Even 1.5 miles (2.4km) away, the noise from a Saturn V launch was recorded as being 120 decibels

Gets you 101.6 decibels from 20 km away.
Okay, how about 200 km over water? 81.6 decibels. Okay as a yearly event, not something that should happen every week.
Okay, how about 2000 km over water? 61.6 decibels. What was the point of this idea again?
Because people like Elon and Gwynne have knowingly lied or purposefully mislead the public regarding Space X.
An example is the Point to Point travel, this is not every going to happen. Anyone with a bit of knowledge about rocketry etc. knows this has a zero percent chance of happening alone because of the noise it would case. In their presentation they had Zürich as a destination, Zürich is so small that you would blow out every window in the entire city. Launching starship in Zürich will never ever happen.
