Answer 1

SPContext.Current runs outside the RunWithelevatedPrivileges elevated context. For more info see this blog post.

Answer 2

You're setting your SPWeb to SPContext.Current.Web, this doesn't have elevated privileges. Only SPWebs created from SPSites created inside the delegate are elevated.

So you need to replace

SPWeb web = SPContext.Current.Web;

with

SPWeb web = site.OpenWeb(SPContext.Current.Web.ID);
