I agree. Too convenient? I don't quite buy that--not that you argued
it. First, Dr. Bussard grows no younger. The publicity burst, such as
it was, might have no more motive than him wanting to make certain his
recent work has a good chance to continue after his retirement or
death. Second, necessity mothers invention. No one had any interest in
electric cars when gasoline cost pennies per gallon.

Agreed. I'll fund it if I win a lottery jackpot. Realistically,
perhaps a fund drive to gather attention for the project? A la the
Methuselah Mouse Prize, or through Fundable.org?

Trees have many advantages, but not power density. You can build
spaceships with trees, but only the paper kind.
Sometimes the delete key serves best.
