I don't think it's that simple, Brian. If we settle a Great Merchant, we get +1 food and +6 gold until the end of the game. Say we get the great merchant on turn 100 and the game lasts until turn 400 (of 500 total possible turns). Settling would yield 300 food and 1,800 gold.
If we use the Great Merchant to bulb, we get 1,000 + (3 * total population). Assume our population is 15 when we bulb, that yields 1,045 beakers. Currency costs 624 beakers, so 421 beakers are wasted, yielding 624 beakers. We can also count as a benefit the earlier trade routes from getting Currency faster. Because we will eventually get those trade routes through manual research, we can only count them as a benefit for the earlier turns, not for the turns after it would be manually researched. Say we are generating 20 bpt at break even, we could research Currency manually in 31 turns. During those turns, we're unlikely to have any multipliers (libraries, markets, etc.) to calculate. If we are getting +5 trade from the extra trade routes, that's a benefit of 155 trade. We also get the less quantifiable benefit of researching something else during those 31 turns, thus getting other technology faster. So the total benefit is 624 beakers + 155 trade + 31 turns faster research on another tech.
So, we're comparing settling (300 food and 1,800 gold spread over 300 turns) vs. bulbing (624 beakers + 155 trade spread over 31 turns + faster research on another tech). I personally think bulbing is the better choice, because earlier stuff yields greater returns over time.
Edit to add that trade_mission_gold = 500 + 200 * trade_profit_between_target_city_and_our_capital, so early it's not great but later it can be quite profitable and better than bulbing.
