Not all VCs operate on the "we just need 1 unicorn" model. Some VCs are a bit more conservative and would be happy with a 4-5x return on their money.

What's nice about the seed-strapped model is primarily optionality (which is good for you and also good for seed investors). Meaning you can start out with a seed-strapped mentality and flip to a "Big VC" mentality later on IF it makes sense. IMO during seed stage, most founders won't know upfront whether they would benefit from a huge capital injection or not, so IMO it's best to start with raising a small amount and then raising larger amounts later if/when you want to.

Again, VC is 100% a game. You need to know how the game is played in order to know whether you want to play it in the first place. So many founders don't understand VC/Founder dynamics, especially first time founders. Starting with a seed-strapped model gets your feet wet in the VC game without diving head first.
