Other way around: Easier tickets is an incentive for volunteers, as a bit of a payment in kind. It helps people known to volunteer come back, and it encourages them to keep volunteering year after year. You need to work, honestly, ridiculous amounts of hours to get a voucher (15-20 hours), and so it'd not be a very good incentive for average person.

You can absolutely get tickets on public sales by knowing when sales start, refreshing on the dot and doing the captcha as fast as you can. Reducing your latency (ethernet, fresh browser profile without extensions) helps. Add some friends into the mix and you'll get all the tickets you need.
