As for the lake, it's just the means to even more peace of mind and a place to enjoy my time in a peaceful healthy environment.

And you can put seastead in the middle of the lake!
er, that would be a lakestead (under a "personal" flag)

Reminds me of this lil pic (not by me):

Lakestead?
DIY!

a cool pic...I am imagining an underwater "Dr Evil"-like mechanism that activates ashore and extends the pier toward the house, then rapidly (relatively speaking) "snaps" back.
