There is a massive difference between a government seizing its way to a reserve or taking their own money to build a reserve.
Well, two things:
First, I don't really understand your problem with the poll.

It's three different options: two with a government only keeping
seized coins, and one with the government actively
buying coins. The "holding seized coins" is more likely in countries without an extreme pro-Bitcoin strategy (say El Salvador) -- even Trump's proposal is "only" hold seized coins, not to buy actively. Maybe you mean that I should have included an option with the government actively buying, but only a limited amount, so the poll is more complete? (Yep, if this was a scientific study, I probably would have designed the poll with that option ... but for a forum post I think it's better to simplify sometimes.)
Second, I don't see such a large difference between both strategies. Not selling seized coins is basically accruing opportunity cost, because if you auctioned the coins (like the LKA Saxony did) you would have an income in fiat, but holding them means renounce to that income. Basically it's the same thing like buying coins actively for the same amount.
The only real difference in my opinion is predictability. The amount of seized coins is difficult to predict. However, for example the first El Salvador buys were also not really systematic - Bukele wrote always he "bought the dip", but the dip went deeper and deeper in 2021/22 ...

El Salvador shows also other options for a country to get the coins, like
BTC income from taxes and fees, like in the case of El Salvador's residency and investment programmes.
First and foremost it was a clarification for myself because I am working on my post, which is going to be pretty long and detailed and will be about skin in the game and how that impacts a government's behavior towards Bitcoin (Nash equilibrium etc.).
I see a
HUGE difference in both strategies. If a government says they are going to actively build a reserve with their own national currency, then their stance on the matter is fundamentally different and also, just imagine what kind of ill-considered incentive there would be for authorities if they say they seize their way to their own substantial reserve? It would actually be bad news for the Bitcoin community as that would certainly imply a more hostile stance on Bitcoin, imposing more restrictions on how to use Bitcoin and for what purposes and so on and so forth, creating more space to justify seizures. If a government steps forward and says they are going to take their national currency in order to build a Bitcoin reserve, the chance that they are going to harm the network by passing laws that undermine the core principles of Bitcoin is far less likely.
From a game theoretical perspective, the two scenarios "seizing" vs. "buying" couldn't be more diametrically opposed, not to mention the countless complex implications both scenarios would entail for all Bitcoin stakeholders.
As for Trump saying he aims at only holding seized coins, the dude is so messed up in his brain that I doubt he'll take action concerning Bitcoin based on what he said a few months or even a few weeks ago. He has no clue. The geopolitical relevance of Bitcoin is likely to grow and if Trump can't see it, some of his staff might see it. Things could change quickly, Elon Musk just changed his mind about Bitcoin again and said it has merit after he said it's crap and he is going to support DOGE.
Trump is erratic and if Musk shows up as an advisor and tells Trump to further look into Bitcoin, then Trump presents it as an excuse and says something like "my tech guru friend Elon told me to have a closer eye on Bitcoin and since he is a genius, I will do it". (could literally be a post on X/Twitter).
Oh and last but not least: to get back to the beginning of your post and the poll, well, it is not about being scientific when it's about adding the option whether it would be desirable if a government decides to buy tons of Bitcoin. I would actually advocate it. If a government with true intentions decides to convert national currency into large amounts of Bitcoin, then yes, go for it. If a government is only building their holdings through seizures, then my answer would be no, not good. It's simply a fundamentally different consideration if you ask me.
I will explain in my announced post why I think governments holding
purchased (and rightfully seized) Bitcoin can clearly be a good thing.
