Yeah, I read all these comments and they miss the obvious answer.
Pitch large vcs and ask for a lot of money.
It goes against the YC grain, but it is the reason there are silicon valley vcs. It used to be that starting a company meant building chips and buildings and assembly lines, and some vcs are structured to write 30m series a, 50m total to build product, and then 50 to scale. A friend of mine is doing this in the database world right now.
If there is a 15m regulatory barrier, then your pitch is why your team is the right one to bet on, and you raise 30m. The money is out there, you can take it
