Yes, no doubt with that. Still we can say two things.
1. They(lawmakers) like it because they can use it for their next level corruption.
2. No, they don't like it because of its transparency and they'll be caught in the act if they support it.
You can't use Bitcoin for corruption in this sense. It is the worst instrument that you could possibly consider for corruption. There are ways that you can cheat like overpaying for it through intermediaries that charge extremely high fees, but any such corruption will be obvious right away. If you buy Bitcoin at $120k a piece, but average price is $110k during this period of time it is clear that you stole money. Also it is very easy to audit a Bitcoin reserve, so it is very difficult to try to hide any fake purchases too.
You don't know the style of our government. They can use everything for corruption as long as there is money involved in it. It's not about the price of Bitcoin that they'll buy and the time and date when. But it is the allocation that they'll play around it. We know how our government works and it's been cooking us with our own oil, using our taxes in the wrong way and that's why even if it's auditable and such. They can always play around with the papers and the auditing through a loop that they can since it's also volatile. But that's the next level that they will find out.
