I'm sorry but there's no way 120 dollars to access a pc for a year is too much. PC's, as cheap as they have become, are still in the range of 400-600$ for last gen hardware and will last you at most for 5 years (and that's being way too nice). Even if it will only last for 3 years, that is still more expensive than 120$/year. I get it not every country can afford 120/year, but that's not LS's problem to be bluntly honest. They want to expand globally and make localised services like Steam, which has a russian-only version where they can only buy and run their games there but has lower prices, however those are long term goals.
In the meanwhile, you will be able to have 3 hours of free, ad supported daily access in march, so I don't think it's valid to ask for a lifetime subscription because severs have to be paid for and will get upgraded over time which means more money has to keep flowing in constantly.
What I would not be opposed to is a yearly plan. I keep my 80hours/month but instead of paying 10 dollars every month I would pay 100 or 110 in one yearly payment, giving me a small discount for my yearly investment in LS. This is something many companies do and I could easily see LS come out with such plans when they finally reveal their new subscription plans.
