ghdp probably lives in a region where land doesn't cost a million per acre. Everything is a trade-off.
Sure, so what's the trade-off for allowing micropayments and reddit's tipping on the primary chain?
Bitcoin is ideal for that if you use payment channels. I'm not sure why they aren't doing that right now.
Because micro-channels are only for
recurring micro-payments that can be aggregated to a bigger one later. It's a small subset of micro-payments, certainly not the general case.
Now if you'd please answer the original question.
Micro-channels are also for single payments. Tipping is also recurring. You are simply biased as to their direction. Think of tipping like leaving money on the table. You have to trust that the busboy doesn't swipe it before the server. Pushing settlements forward reduces mining fees and the occasional small single tip is made up in micro-channel fees.
I fixed your omitted context. Your question doesn't have a trade-off. Different topics.
