First of all, please do not pre-empt your argument that people who disagree will do so for the set reasons you outline, it is an extremely poor way of making your point. If you have a point to make then make it well instead making assumptions about anyone who might disagree with you.
I don’t disagree that some version of this will be the way the game goes eventually. However, a better version IMO would be to allow the skills to be trained as you have outlined it would be some sort of finite plex license to use say, capital ships, T2 ships, T3 ships. But that is simply a micro version of what we have now, not a sea-change as you represent it.
The premise behind your argument seems to be that no player will ever ‘max out’ their character. But as @Solonius_Rex points out, if you just need an alt to do a specific thing e.g. be a fleet PVP pilot, Rorqual mine, be a cyno alt, be a cap pilot the cap of applicable skills goes right down. As you outline it, people could easily have 10 different alts one for each thing (as they can already) but never need to pay anything for it. Yes that adds numbers to the game and boosts the ingame economy BUT it also would detract significantly from CCP’s income, which would reduce the amount of money they can spend on the game accordingly.
Another point is that, as you say it, no-one could ever really max out their char because there are ‘years of skills to train.’ Consider myself, as a 12 year vet with 250m sp (and there are a number with more sp than me), my long term skill plan (all 4 races mastery V everything excl. industry/mining) is only 2-3 years from fruition. What need would I have to pay for the game any more if your plan was implemented after 2-3 years? What would happen to the game then as those who pay for the game suddenly no longer need to pay for it simply to let those who do not want to pay for it, play it for free? I think it is fairly obvious, that there would suddenly be no game to play for either omega or alphas and CCP would go bust.
As I say, I do not disagree that some version of this will be the way the game eventually goes; I think it is a shame that CCP did not make sub-cap T1 alpha free to play excl. niche roles such as mining and cyno alts, and then have a T2 or T3 plex license to use such ships and weapon types for alphas. That would have worked even better a few years ago before they balanced all T1 ships as well so suddenly they were a viable choice to using instead of a T2 ship. But that could work I guess.
I have seen ideas such as yours before whereby an alpha pays a set price to use, for example, HACs. But at what price would an alpha find that acceptable? 3 months subscription to use HACs in perpetuity? I just don’t see the people who you claim to represent being prepared to shell out $45 if you are not even now prepared to shell out $15 a month for that same privilege.
If the game was to start now then I guess a version of what you are saying would be the model by which CCP operates. But since the game has already been operating for 15 years, the problem for CCP is how to change the game into that model without its existing revenue stream suddenly realising they dont need to pay any more. As you outline it, your idea simply does not make good business sense.
So it is a solid no from me, and not simply because I am an Omega, but because I want to still be able to play this game in 5, 10, 15 years hence, and not just look at the good times I have had as a fond memory.
