Your proposal is what POS offers, BTC already rewarding miners and that is strong enough economic value. The best way to benefit from bitcoin and accumulate more if you're not a miner, is to buy low and sell high and repeat same with the hope you won't get caught by the market.
Thats the point, the price could drop in any investment, it is up to you to profit from it or be upset about it. If you are simply just upset because the price dropped, then you are going to do nothing and you are not going to benefit from it, crying over the price and deflation (which is none if you ask me) is not going to solve any of your problems and would just be empty whining.
However, if you buy more when the price drops that means you are going to end up with some profit and that is the way you could get out of this with less harm done to you and more profit chances when the time comes. Thats the only beneficial method during any of the bear markets that we have faced so far.
when you go into the one of the investment markets, of course, you want to get profit later on. so just hodl if you truly believe on this market. that one day, you can reap your rewards of holding. but if you are not very sure about this market, better look for other assets (tangible ones preferably) if you do want to diversify and make sure you will not be at the losing end if one of them failed your expectations.
