Right now I can get an SSL certificate and register a domain name for under $30 through Dreamhost.
I can think of a few projects that I've started that have helped a few people that never would have gotten off the ground if we had your preposterous $1k fee for registrations.
The current system's not great, sure, but it's a whale better than your "only the rich can register" plan.
I have never had more than $2,000 in a bank account at one time. I think that your expectations are slightly skewed. And buying an SSL certificate may be more expensive, but it's still $50/year, a far cry from $1k.
edit: It'd also be likely someone would startup some 'free/cheap' subdomain hosting for people who don't want to pay the $1000... eg myapp.free.com
