you're trying to loop through out web applications with current site's application pool account.

SPSecurity.RunWithElevatedPrivileges uses current site (in your case SPContext.Current.Site) application pool account while you're trying to access farm level web applications.

Check if your site application pool account has enough rights to access other web applications. Usually this is SP_farm account.

Check if following code can help you,

SPFarm farm = SPFarm.Local; 
SPWebService service = farm.Services.GetValue<SPWebService>(""); 
foreach (SPWebApplication webApp in service.WebApplications)
   //Your Code here
