I don't think so. bitcoin has been updated since it was born.

And it is very important to keep it up to date.

So, i don't think the actual design protect it from bad usage, and fees are certainly not enough.

Would you pay 0.001BTC of fees to more 0,0001BTC?

For me we have to maintain a reasonable fee for transaction and this would be possible only if you prioritize money transaction, always.

And it is possible with filters and by design update.

Don't expect the design to regulate itself in the perfect way. They will be winner and looser. On which side you want to be?

The only valuable regulation are the node that don't take any fees to control transactions.

And one last thing, why, ethereum that is used for all extra data storage with fees is not more used than bitcoin ?
