You could plan to use the stamps later and think of it as a loan to help the USPS through a pandemic and a hostile administration. Of course this means limiting yourself to a quantity you can actually use. Forever stamps roughly match inflation, so you're not even losing money in real terms, so it's not a horrible return. I don't use a lot of stamps myself, but I know someone who sells stuff on Amazon, eBay, etc., so if I bought $100 of stamps now, I could probably get them to buy them at full face value from me later. (It also looks like you can sell unused stamps online but only at around 70% of face value.)
