Although my account tells me you are never fully protected from personal liability by setting up a corporation. The court system always has some leeway.
After all, spending money you haven't received yet is the basis of accrual accounting.
Of course, I wouldn't borrow money on a web startup project. That's a whole nother can of worms. But that's not what his business was.
Sounds like he got behind the power curve when he lost the discipline to run an accrual business. It takes a lot more attention to detail, which he didn't have, unfortunately.
A classic example is starting/owning a restaurant or bakery.
Ego, lack of creativity, and laziness are among the only impediments to starting most businesses. You just have to want the end result bad enough that you are willing to work hard on a smaller scale until you can fund your dream. (You can work as a caterer, personal chef, food delivery service, and/or sell your food on consignment at other locations to raise the funds for your own place. MANY restaurants will let you borrow their kitchens for 'free' in exchange for cleaning up or for doing prep work or cooking specialty items. Some may want you to cover the increased insurance risk, but you can still get started in a licensed facility for a small cash outlay. Most independent restauranteurs understand what it is like to start a new food-related business, and many are likely to help you out unless you're an ass or a direct competitor. Then, you can just build up a base of customers and cash until you can buy or lease your own place. If you have good products, and are smart with your cash, it doesn't actually take too long to get enough of a bankroll to go out on your own. It took one of my friends only 11 months as a 'virtual cupcake consignment company' to MAKE the funds she needed to open her own bakery, and she even bought her real estate outright.)
Side note: One of the ladies I assisted in starting her own bakery ended up closing it and going back to bakery consignment and catering because it was less stressful and more lucrative for her than retail. Some of these "ramp up" businesses may be better in the long run than actually owning your own retail/restaurant space.
You're totally right. Going into debt is something one should definitely avoid.
If that is the case, corporate funding for your research (assuming it is going somewhere) is fairly easy to obtain. Also, if your standing in the field is good, and you can articulate your ideas/goals well, angel funding should also be obtainable without much trouble.
In both cases, you are not borrowing money which you have to pay back someday. It is others who are taking a risk funding your ideas. If the risk is good, they get returns, otherwise its their money down the drain. And unless you commit some sort of fraud (embezzle the money as opposed to using it for real product research), you cannot be sued.
