I think, aside from the server issue, it's wrong to consider beta access any kind of "early game access".
To avoid the complications of being funded by a publisher, this game is being crowd funded. As rewards for funding the game at various levels, people got the right to be alpha testers and beta testers, etc. This is not early access of a finished game, this is testing of an incomplete game where final decisions about various things haven't even been made yet, and where Developement is active, ongoing and driven by community feedback. There are entire parts of the game missing and there are placeholders for various things in place during these testing phases. People are finding problems and submitting bug reports for the devs to fix the issues prior to the next testing phase. It's certainly not "early access" to a game.
If you are after early access to a pretty much complete game, that is going to be available later and can be pre-purchased now. It's called "gamma access" and will be playable after beta has completed, before the official launch (beta hasn't started yet, so it will be a while). Gamma is not $150.
At that stage, it should be pretty much a finished product, with maybe only a few tiny flaws and balance issues to work out, ready for the official launch at a later date. I would think that by that time the net code will be improved, servers will be located where they are needed, and everything should be running fairly smoothly. Don't buy beta if you don't want to test an incomplete and partially broken game.
