As a founder of a company that's raised $25M combined over our seed, Series A, and Series B, I think Sam's coming from the right place. We raised a $2.5M seed round and a $7.5M Series A. At no point during our seed and Series A (the time period you're talking about) would it have made any financial sense for the founders to cash out even a penny. We felt this way because we had and still have genuine intentions of building a huge company, and every penny should be invested in growing the company. If we had instead felt differently, we would have tried to cash out some of our equity (which we didn't), and that should have been a red flag for investors to stay away.
There's nothing wrong with trying to build a company to flip it for a few million in a year. Even better if you can do it without taking any outside money. If I were even an angel investor though, I would run away if I had any suspicion that that was the case.
Also, if your company is worth $5M on paper due to investor term sheets, there isn't any really meaningful way you can achieve financial security unless you sell almost your entire stake in the company, which investors obviously wouldn't want to partake in. $5M from a term sheet doesn't meant $5M of liquidity.
As an aside, I think your reply is incredibly immature, but I'm not going to use that as an argument for why you're wrong.
