How important is owning the stadium?

I believe the club have a 99yr lease at a few million a year or something silly.
Other clubs have had to take huge loans with massive interest rates that they have to pay to build a new ground. 
I don’t understand how West Ham can have any money problems whatsoever?
Why would we better off owning the stadium as if its land value, well, your using the land to play football so there is no other use for it.
Plus, clubs like Liverpool & Everton own stadiums in cheap areas of the country so it feels like ownership doesn’t really mean much.

Not sure I get it? (Apart from having the right to tear it down and rebuild something better).
