Much like you, my sp is from author rewards. Personally I don't care much if steemit goes to the shitter. It has already helped me in my real life in other ways, which directly and indirectly result to both monetary gains but most importantly... fun! Not to mention that I have made some nice trades and gifts to myself from the steem I have cached out :)

By the way, @steem-peg is making me really positive for the future lately as the wallet seems to get bigger and bigger by the day! Clearly, there's an interest in all those shitty tokens which if my logic is correct means:
i) less steem available for sale in the exchanges, which is good
ii) people actually buying and burning steem to create or buy these tokens. Or at least they don't sell their auth rewards and instead "lock them" in steem engine to buy poop tokens. This is good too.

Edit: Yeah I forgot to answer your question. I will go for answer g:
