M2S held everything pre-sparks under the Intrusion 1.0 system, for which you had to sign up to show up and be eligible to do SAPs, and it was only twice a week. Currently in the Intrusion 2.0 system if you've noticed, SAP's are happening twice a day per outpost usually. Therefore, your argument is invalid.
With the changes Zoom is putting in with regard to field terminals and the taxation system, coupled with the facility point rebalance, will make Beta worth living on for corporations. Spark removal will insure complete world domination will be more difficult.
Coincidentally, the taxation system will provide an incentive to solve conflicts before they blow up into full blown wars, and cooperation will be a viable (and lucrative) alternative to extermination by default. NRDS will be a viable alternative.
Although regardless of any changes, JOKE and a few other corps won't own outposts, because POE will say no. Newbies on the other hand... good luck to them, hope they enjoy the game.
