Yurt platform on grade versus sunken piers

[Asheville Yurt Company]

For your consideration, one of the disadvantages to being close to the ground is dampness. You want to be off the ground at least 2 feet, preferably 3, with a ground cover under there to keep the damp from rising. This will help with the humidity issues but it also exposes you to wind issues so generally an elevated platform is enclosed with skirting as well as having the footers. Your call tho.
