Just made me thinking...
...how much work/cost would be allowing also rental model for people who struggle with basic math and concept of saving money (although I can imagine life situations where even 1k TL could be difficult to save over year, but maybe such person should focus on other things in life than PC and games)?
(this is not serious suggestion, sorry Scawen, just dumping overloaded brain. I like the lifetime license - shows moral integrity of developers which is welcome change in today's world for me ... well, one really far fetched option would be monthly rental until some total sum (like ~150% of S3 price) is paid over time and then changing rental license to final license, thus being "money lender" business on LFS dev team and making everything more complicated, although maybe lowering entry barrier for people like OP)
