If you don't know anyone in the community, purchasing a ticket online is a crapshoot. IMO this is a feature not a bug.
2) Hackerspaces get a number of tickets with priority, thru replicating tickets (you can only buy one per day). The amount of replicating tickets given depends on size of area (a hackerspace can be tasked with giving vouchers to relevant people in their city). There's a limited quantity of these tickets, separate from amount of vouchers.
The main point of the congress is primarily to bring the chaos crowd together, then the rest of interested parties. That model may not fit your vision, but chaos events year after year succeed at not leaving out the core crowd.
Also, this year I have bought 2 tickets on public sale for friends without issues (best way to get tickets is to group up with your friends).
It's always taken high effort to buy tickets for c3, needing to be exactly on time (not 30 seconds late) to each sale round.
37c3 was an exception due to low sales, caused by skepticism in the event returning after years of not happening. This year that trust was regained and buying tickets became hard again.
But it's ok, I can watch it online. I don't like travelling during this busy period anyway.

Some things are pretty cheap compared to other countries, meat for instance
But I didn't mean to complain, just to say it's not only the ticket availability that's a factor.
And this is not something the organisation can help of course. It's a German event so of course it's in Germany. And the tickets themselves are well priced.
And like I said, I really appreciate them making everything available online.
I do tend to go to the Dutch hacker camps that are being held once every 4 years.
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.
Tickets are not that hard to get and you are not required to do anything once you have one.
I believe some core orga members (aka The people contracting the venue, getting permissions and renting equipment etc) are guaranteed a ticket but almost everybody else has to buy their own.
The fact that the "hacker space community" gets preferential treatment is very much intended.
