We don't know, the permitted crowds at Elite Level had not been announced. I heard from people at a couple of other clubs it was to be calculated per ground not as a flat %. Given some obvious pinch points I suspect the current ground wouldn't have fared too well in the assessment.
Aldershot, who have much more room in the ground, had stated they anticipated being able to permit 2k once fans were admitted. They also have a few issues, toilets etc
If the season does start in front of fans (looking very unlikely now) I doubt you'll be allowed to hibernate without relegation. (It's a bit different for teams outside England, due to the potential for devolved government rules hitting them.)
To be clear, if sitting out the season and being relegated was the only way to save the club, I'd support it. I just don't think sitting the season out is an easy answer.
It's worth noting the official advice in Merseyside etc is that people now should not attend sport as a spectator. That has the potential to cause a world of pain for tier three and below in the impacted parts of England.
