Why do you need connections to open a bar? Can't you drive without connections?
If you have no connections, no one will come. Why do so many bars come to your house? This is why many bars invite people to warm up at the beginning of their opening. Both men and women don't need money, even if you can attract guests, you can get free for life. Go to the bar just for fun and fun. Might as well open coffee. Of course, there will be silence. Investment takes time, and you need to be able to accept that you have no money for a year or two and keep throwing money at it. Stick to it and you may not live long.
