I'm not sure if it's officially a formal grammer, but there are definitely correct and incorrect phrasings for certain effects, and those are changed over time with official rewordings posted for old cards.
It's one of the ways that unofficial card spoilers are judged. If there are phrasings that sound "out-of-style" for the effect, its usually judged as a fake from the first pass.
Owning land that has gone through 3 or 4 generations in the same family, while technically an "investment asset", usually isn't treated the same way from a planning perspective as, say, apartments you purchase with the intention to liquidate upon retirement. There may be a lot fewer ways to generate revenue from it, so in all reality you may barely be breaking even on upkeep. You're then forced to decide between giving your children an excellent education which will set the up well in life vs keeping the land which you have a strong emotional attachment to and wish to share with future generations.
I'd argue that those sort of investments would be better gated by knowledge than available finances. There's no reason a early employ that made <$1m in a buyout shouldn't be allowed to invest 10k in another startup. He absolutely knows what he's investing in, and it's his choice if he's willing to take that risk.
I think it's sad that we've gotten to the point where we're telling people who remained consistent over time to "be more like the politicians, and just lie to suit the masses." It seems like we'd be complaining about that in a different post.
I only have a vague memory/understanding the subject, but I believe the Bitcoin protocol supports the concept of multi-signature contracts. That could be used to create decentralized escrow/trading/exchanges, which means that you would never have to let a single entity control your private keys. (https://en.bitcoin.it/wiki/Contracts)
I don't think there is a working implementation of the multisig contracts in the wild yet, but the protocol does support a way to solve these problems.
